Section 12.12.3 Building Separation and Section 12.8.7 P-Delta Effects
The Code Simple column published in August 2008 explained what role the Importance Factor, I, has in the determination of drift. In this Code Simple, we would like to take a closer look at Section 12.12.3 Building Separation and at Section 12.8.7 P-Delta Effects.
Qualifications-based selection is valuable to the client
Among the most important decisions a client will be required to make is the manner in which the client selects the engineering firm to perform services being procured. In selecting an engineering firm, the client must always recognize that it is not acquiring a predetermined product. Instead, it is acquiring the professional engineering skill, talent, and effort necessary to achieve the client’s ultimate objective.
Painting as a pastime: Avoiding career burnout
Prime Minister Winston Churchill, President Dwight Eisenhower, and velvet-voiced crooner Tony Bennett of "I left my heart in San Francisco" fame had one thing in common. They were all self-taught oil painters who pursued this pastime for relaxation and mental rejuvenation. (Bennett still does.) Although they favored landscapes, each dared to paint portraits as well.
With rising prices on a global scale, engineers, architects, contractors, and owners are all looking for cost-effective options within traditional structural steel products and design software. These suppliers are up for the challenge, offering software that builds on current systems and products that allow for difficult applications, while maintaining sensitivity to environmental impact.
Structural engineers and disaster response
Post-disaster safety evaluation has evolved over the years and matured in California into an effective, well-defined system. Structural engineers are an integral part of the state’s ability to respond to disaster inspection needs through the Safety Assessment Program (SAP). This article explains the history of the program, as well as how the current program works, with the aim of educating structural engineers across the nation to build the post disaster community and create resilience.
Efficient floor framing systems Preliminary sizing of post-tensioned floors
When designing for thinner floors, using post-tensioning to resist loads and deflections provides a more optimal solution than conventionally reinforced floors. This fact is primarily due to the load-balancing effect of the draped post-tensioned tendons.
