Building Structural Maintenance

φ
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.
φ
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.

ASCE/SEI 41-17 (Seismic Evaluation and Retrofit of Existing Buildings):  Focuses on assessing and maintaining existing structures, particularly for seismic performance.  Guides retrofitting to address vulnerabilities like cracking or inadequate load paths.
Maintenance Standards
  • ACI 562 (Assessment, Repair, and Rehabilitation of Existing Concrete Structures):
    • Provides a framework for evaluating and repairing concrete structures to address cracking, spalling, or other damage.
    • Emphasizes regular inspections and timely repairs to maintain structural integrity.
  • NACE/SP0108 (Corrosion Control of Offshore Structures):
    • Covers maintenance practices to prevent corrosion-related failures in steel structures.
  • ASTM E2270 (Standard Practice for Periodic Inspection of Building Facades):
    • Outlines procedures for inspecting facades to identify cracking, water infiltration, or other issues that could lead to structural problems.

Exploration of the Theory of Electric Shock Drowning

Exploration of the Theory of Electric Shock Drowning

Jesse Kotsch – Brandon Prussak – Michael Morse – James Kohl

University of San Diego

Abstract:  Drowning due to electric shock is theorized to occur when a current that is greater than the “let go” current passes through a body of water and conducts with the human body. Drowning would occur when the skeletal muscles contract and the victim can no longer swim. It is theorized that the likelihood of receiving a deadly shock in a freshwater environment (such as a lake) is higher than the likelihood in a saltwater environment (such as a marina). It is possible that due to the high conductivity of salt water, the current shunts around the individual, while in freshwater, where the conductivity of the water is lower than that of the human; a majority of the current will travel through the individual. The purpose of this research is to either validate or disprove these claims. To address this, we used Finite Element analysis in order to simulate a human swimming in a large body of water in which electric current has leaked from a 120V source. The conductivity of the water was varied from .005 S/m (pure water) up to 4.8 S/m (salt water) and the current density through a cross sectional area of the human was measured. With this research, we hope to educate swimmers on the best action to take if caught in such a situation.

Swimming Pool Dimensions and Construction

University of Michigan | Washtenaw County

About Last Night: #Paris2024

A standard Olympic-sized swimming pool is defined by the following dimensions:

  • Length: 50 meters
  • Width: 25 meters
  • Depth: A minimum of 2 meters
  • Lanes: 10 lanes, each 2.5 meters wide

The total area of the pool is therefore 1,250 square meters, and it holds approximately 2,500 cubic meters (or 2.5 million liters) of water.

https://standardsmichigan.com/australia/

The organization that sets the standards for Olympic-sized pools is the Fédération Internationale de Natation (FINA) — now World Aquatics — the governing body for swimming, diving, water polo, synchronized swimming, and open water swimming. FINA establishes the regulations for the dimensions and equipment of competition pools used in international events, including the Olympic Games.

The top ten universities that have produced Olympic champion:

  1. University of Southern California (USC)
  2. Stanford University
  3. University of California, Berkeley (UC Berkeley)
  4. University of Florida
  5. University of Texas at Austin
  6. University of Michigan – Michael Phelps, the most decorated Olympian of all time.
  7. Indiana University
  8. Auburn University
  9. University of Georgia
  10. University of Arizona

Baseball Lighting

The College World Series begins this weekend in Omaha between Louisiana State University and Coastal Carolina.

 

Baseball is a pastoral game and lighting changed the experience of it. Since a baseball is less than 3-inches in diameter and routinely travels 400 feet at 100 miles per hour, illumination design must have outfielders in mind as well as other players and spectators.

and the other half is physical.”

After athletic facility life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

 

During the spring baseball season the document linked below provides guidance for illumination designers, contractors and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We cover the objectives of the energy conservation advocates in separate posts; notably advocates using the International Code Council and the ASHRAE suite to advance their agenda to press boxes and the entire baseball experience (interior and exterior) site in separate posts.

We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next Sport colloquium.   We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

Recreational sports, athletic competition, and the facilities that support it, are one of the most visible activities in any school, college or university in any nation.  Arguably, these activities resemble religious belief and practice.   Enterprises of this kind have the same ambition for safety and sustainability at the same scale as the academic and healthcare enterprises.  

According to IBISWorld Market Research, Sports Stadium Construction was a $6.1 billion market in 2014, Athletic & Sporting Goods Manufacturing was a $9.2 billion market in 2015, with participation in sports increasing 19.3 percent by 2019 — much of that originating in school, college and university sports and recreation programs.  We refer you to more up to date information in the link below:

Maths and Sport

The use of “maths” instead of “math” is a difference in British English compared to American English. In British English, the word “mathematics” is often referred to as “maths,” with the added “s” signifying the plural form. This is consistent with how British English commonly shortens many words by adding an “s” to the end. For example, “physics” becomes “phys, “economics” becomes “econs,” and so on.

In contrast, American English typically shortens “mathematics” to “math” without the additional “s,” following a different pattern of abbreviation.

The reason for these linguistic differences is rooted in the historical development of the English language and regional linguistic variations that have evolved over time. British English and American English have diverged in certain aspects of vocabulary, pronunciation, and grammar, resulting in variations like “maths” and “math.” It’s important to note that neither is inherently correct or incorrect; they are just regional preferences.

 

 

 

 

 

 

 

 

 

 

 

 

 

Gresham College is a higher education institution located in London, UK. It was founded in 1597 under the will of Sir Thomas Gresham, a financier and merchant who left funds for the establishment of a college in the heart of the city.

The college’s original aim was to provide free public lectures in a range of subjects, including law, astronomy, geometry, and music. The lectures were intended to be accessible to anyone who was interested in learning, regardless of their background or social status.

Over the centuries, Gresham College has remained true to this mission, and today it continues to offer a range of free public lectures and events that are open to all.
