Wood lateral systems enable engineers to produce a building designed to resist high wind and seismic loads for little or no extra cost. Find more information on diaphragms and shear walls on APA’s ...

The resilience of modern structures under seismic and lateral forces is highly dependent on the performance of slab‐column connections. These joints are critical for transferring loads ...

Wall bracing is what makes those buildings perform well against lateral wind and seismic loads,” said Dr. Borjen Yeh, P.E., director of APA’s Technical Services.

Shear walls are walls specifically designed to resist lateral loads, transferring the load from the wall above to the wall below and, ultimately, out through the foundation. This is a critical role in ...

The research is devoted toward documenting the seismic performance of timber bridges in past earthquakes; assessing, from both theoretical as well as experimental perspectives, the strength and ...

Reinforcing ribs were shown to be effective against lateral forces and improve load-bearing capacity. Their work points bridge engineers to rational design strategies to make more resilient ...

Rebuilding Terminal 1 in a seismic zone? Here’s how San Diego International Airport tackled earthquake risks head-on.

Project-specific seismic/wind calculations can be provided for the roof curb, the connection of rooftop equipment to the roof curb, and roof-curb connections to the building structure. Calculations ...

Abstract: This report presents an analytical and experimental investigation of the coupled horizontal-vertical response of elastomeric and lead-rubber bearings focusing on the influence of lateral ...
