Any multi-story building requires inspection and maintenance of structural steel framework. The steel supports the building’s weight and resists environmental forces like wind and seismic activity. Over time, corrosion, fatigue cracks, or connection failures can weaken the structure, risking collapse. Inspections detect these issues early, while maintenance, like repainting or replacing damaged parts, preserves steel integrity. For student housing, occupant safety is critical, and compliance with building codes reduces liability risks. Neglecting these practices can lead to structural failure, endangering residents and causing costly repairs or legal issues. Regular upkeep ensures safe, long-lasting buildings.
During today’s session we examine the relevant standards with proposed revisions open for public comment. Use the login credentials at the upper right of our home page.
No single universal code or standard guarantees that buildings will never crack or fail structurally, as structural integrity depends on various factors like design, materials, construction quality, environmental conditions, and maintenance. However, several widely adopted codes and standards aim to minimize the risk of structural failure and ensure safety, durability, and serviceability. These provide guidelines for design, construction, and maintenance to prevent issues like cracking or catastrophic failure.
φ
Key Codes and Standards:
International Building Code (IBC): Widely used in the United States and other regions, the IBC sets minimum requirements for structural design, materials, and maintenance to ensure safety and performance. It references standards like ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) for load calculations (e.g., wind, seismic, snow).Maintenance provisions require regular inspections and repairs to address issues like cracking or deterioration.
ACI 318 (Building Code Requirements for Structural Concrete): Published by the American Concrete Institute this standard governs the design and construction of concrete structures.Includes requirements to control cracking (e.g., reinforcement detailing, concrete mix design) and ensure durability under environmental exposure.Maintenance guidelines recommend periodic inspections for cracks, spalling, or reinforcement corrosion.
AISC 360 (Specification for Structural Steel Buildings): Published by the American Institute of Steel Construction, this standard covers the design, fabrication, and erection of steel structures. Addresses fatigue, connection design, and corrosion protection to prevent structural failure. Maintenance involves inspecting for issues like weld imperfections or coating degradation.
Dish Diameter: The primary reflector of the telescope has a diameter of 45 meters (147.6 feet). This large size allows it to collect radio waves effectively.
Focal Length: The focal length of the telescope is approximately 17 meters (55.8 feet). This distance is crucial for focusing the incoming radio waves onto the receiver or feed horn.
Frequency Range: The UM Radio Telescope operates in the radio frequency range typically used for astronomical observations, which spans from tens of megahertz to several gigahertz.
Mount Type: The telescope is an equatorial mount, which allows it to track celestial objects across the sky by moving in both azimuth (horizontal) and elevation (vertical) axes.
Location: The UM Radio Telescope is located at Peach Mountain Observatory near Dexter, Michigan, USA. Its geographical coordinates are approximately 42.39°N latitude and 83.96°W longitude.
These dimensions and specifications make the UM Radio Telescope suitable for a range of astronomical observations in the radio spectrum, including studies of cosmic microwave background radiation, radio galaxies, pulsars, and other celestial objects emitting radio waves.
Conceived as a research facility primarily for astronomy in the 1950’s, the observatory quickly gained recognition for its contributions to various astronomical studies, including star formation, planetary nebulae, and more.

“Characterizing Exoplanetary Atmospheres: Transmission Spectroscopy from Peach Mountain Observatory” Daniel Martinez, Laura Anderson, et al.
Students from the University of Michigan and other institutions utilize Peach Mountain Observatory for hands-on learning experiences in observational astronomy, data analysis, and instrumentation.
Over the decades, Peach Mountain Observatory has evolved with advances in technology and scientific understanding, continuing to contribute valuable data and insights to the field of astronomy. Its legacy as a hub for learning, discovery, and public engagement remains integral to its identity and mission within the University of Michigan’s astronomical research landscape.
In the United States, land surveying is regulated by various professional organizations and government agencies, and there are several technical standards that must be followed to ensure accuracy and consistency in land surveying.
The best practice for land surveying is set by the “Manual of Surveying Instructions” published by an administrative division of the United States Department of the Interior responsible for managing public lands in the United States. The manual provides detailed guidance on the procedures and techniques for conducting various types of land surveys, including public land surveys, mineral surveys, and cadastral surveys.
Another important set of model standards for land surveying is the Minimum Standards for Property Boundary Surveys* published by the National Society of Professional Surveyors. These standards provide guidance on the procedures and techniques for conducting property boundary surveys, including the use of appropriate surveying equipment, the preparation of surveying maps and plats, and the documentation of surveying results. Land surveyors in the United States are also required to adhere to state and local laws and regulations governing land surveying, as well as ethical standards established by professional organizations such as the American Society of Civil Engineers.
The Morrill Land-Grant Act of 1862 granted each state 30,000 acres of federal land for each member of Congress from that state to establish colleges that would teach agriculture, engineering, and military tactics. This legislation led to the establishment of many public universities, including the Texas A&M University, the University of Wisconsin and Michigan State University.
Fibonacci numbers reflect standardization in nature through their consistent appearance in growth patterns and structures, embodying efficient, repeatable designs. These numbers (0, 1, 1, 2, 3, 5, 8, …) govern the arrangement of natural forms, such as the spiral patterns in sunflowers, pinecones, and seashells, where seed or scale counts often match Fibonacci numbers.
This standardization optimizes space and resource distribution, ensuring maximum efficiency—e.g., sunflower seeds pack tightly without gaps. Leaf and branch arrangements (phyllotaxis) follow Fibonacci angles to standardize light exposure and growth. The sequence’s recursive nature mirrors nature’s iterative processes, like branching in trees or cell division, providing a universal template for scalable, stable structures.
The golden ratio, derived from Fibonacci numbers, further standardizes proportions in natural forms, from nautilus shells to galaxy spirals, revealing a mathematical blueprint that unifies diverse biological and physical systems.
Fibonacci used a hypothetical rabbit population to illustrate his famous sequence in his 1202 book Liber Abaci. He posed a problem: starting with one pair of rabbits that produces another pair each month, with each new pair becoming reproductive after one month, how many pairs are there after n months? This leads to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, …), where each number is the sum of the two preceding ones. The rabbit scenario was a simplified model to demonstrate the sequence, not a literal study of rabbit breeding. Fibonacci’s work focused on mathematical patterns, not biological theorems.
Fibonacci numbers find applications in electrical power engineering through their mathematical properties, which can optimize design, analysis, and operation. Here are five applications:
Power System Network Analysis: Fibonacci sequences can be used in graph theory to model electrical networks. The recursive nature of Fibonacci numbers helps in analyzing hierarchical or layered network structures, such as transmission and distribution grids, to optimize load flow or fault tolerance.
Transformer Winding Design: The golden ratio, derived from Fibonacci numbers, can guide the geometric arrangement of transformer windings. This helps minimize electromagnetic interference and optimize the efficiency of power transfer by balancing inductance and capacitance.
Signal Processing for Power Quality: Fibonacci-based algorithms, such as those using the golden section search, are applied in digital signal processing to analyze power quality issues like harmonics or transients. These methods efficiently identify optimal frequency components in noisy power signals.
Renewable Energy System Optimization: In solar panel or wind turbine array layouts, Fibonacci-inspired spiral patterns (like the golden spiral) can optimize land use and reduce mutual shading or turbulence, improving energy capture efficiency in power generation systems.
Control System Tuning: Fibonacci numbers can inform the design of control algorithms for power systems, such as in PID controller tuning. The sequence’s recursive properties help in iteratively adjusting parameters to achieve stable and efficient grid operation under varying loads.
These applications leverage the mathematical elegance of Fibonacci numbers to solve practical engineering challenges in power systems.
Like many folk traditions of saying “Rabbit, rabbit” to your colleagues on the first day of the month has an unclear origin and has several variations and interpretations. We use it a reason to explore university research into food sources; the proper business of education communities everywhere. In one version of the tradition, saying “Rabbit, rabbit” or “White rabbit” as the first words upon waking on the first day of the month is believed to bring good luck for the rest of that month. It is thought to ensure good fortune, happiness, and general positivity throughout the coming weeks.
The specific origins and reasons behind this tradition are difficult to trace, as superstitions often evolve and are passed down through generations. It’s worth noting that this practice is not universally known or followed, and its popularity may vary among different regions and communities. Ultimately, the saying “Rabbit, rabbit” on the first day of the month is an example of a charming and whimsical superstition that some individuals enjoy participating in as a fun way to start the month on a positive note.
Athletic and recreational sports enterprises are important features in education communities; supportive of brand identity and cohort creation. Assuring the safety and sustainability of these assets is informed by several best practice titles; among them the Illuminating Engineering Society recommended practice RP-6-15 Sports and Recreational Area Lighting From the project prospectus:
The purpose of RP-6-15 is to provide the reader with recommendations to aid in the design of sports lighting systems. Popular sports, such as baseball, tennis, basketball and football as well as recreational social activities, such as horseshoe pitching and croquet are covered. Venues for spectators of amateur, collegiate, and professional sports are complex facilities that should provide not only for the spectators, but also the equipment used in modern sports broadcasting. This document does not address those needs, so the reader should look for guidance from the sports league or the project consultant. Sports lighting systems consume power which over time can be significant, and IES RP-6-15 defines methods for maximizing energy efficiency.
The IES-suite joins standards developed by the International Code Council (International Building Code), the Institute of Electrical and Electronic Engineers (IEEE 3001.9) and the National Fire Protection Association (NFPA 70) that must be applied skillfully by design professionals and understood by athletic facility managers. Other consensus standards developers such as the American Society of Heating and Refrigeration Engineers and the Entertainment Services and Technology Association were moving into this domain before the circumstances of the pandemic.
We always encourage our colleagues in the education industry to do so themselves; starting with the links below:
Comments on proposed changes to IES LP-6-2x Lighting Practice: Lighting Control Systems – Properties, Selection, and Specification will be received until April 1st
Comments on Draft “IES TM-39 Technical Memorandum: Quantification and Specification of Flicker” will be received until August 12th
Keep in mind that the IES typically deals with the application of best practice in illumination. It neither covers the reliability of the power systems nor the power chain to the luminaries. Recommended practice for the power chain are now being developed by the IEEE Industrial Applications Society; specifically IEEE 3001.9 – Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities. The IEEE Education & Healthcare Facilities Committee pulls together ALL the standards — ICC, IEEE, IEC, NFPA, IES, ASHRAE, ASTM, ESTA and any other emergent consensus or open source documents that might set the standard of care for the education industry.
