The use of high-strength steel bars in reinforced concrete coupling beams is expected to reduce reinforcement congestion. A series of tests was conducted to investigate the effects of high-strength reinforcement on coupling beam behavior. This document summarizes the test program and test data. Read more

Presenting an industry-wide schedule performance measure of construction contractors applicable to any project and at any level of detail. If successful, it will enhance the transparency of project productivity and enable the identification of any under-performing activities, projects, or firms. The performance measure is comparable across all project types, complexities, and company sizes for the construction industry. Read more

When the beam shear demands in coupled core wall systems, commonly used in mid- to high-rise towers, become relatively large, the typical reinforced concrete beam is no longer adequate. It is common, in these cases, to either use a concrete-encased structural steel coupling beam or simply a steel coupling beam. The current requirements for the analysis, design, and detailing for steel and concrete encased steel coupling beams provide for high seismic applications, however, fall short in regard to applications for wind events. The driver for this research is to close the guidance gaps. Read more

Ductile Reinforced Concrete Coupled Walls:
FEMA P695 Study Read more

Composite Plate Shear Wall-Concrete Filled (C-PSW/CF) is an efficient seismic force-resisting system for buildings and is already addressed by ASCE-7 2016. Coupled Composite Plate Shear Walls-Concrete Filled (Coupled C-PSW/CF) are more ductile and have more redundancy than non-coupled composite plate shear walls, but ASCE currently does not assign them seismic design coefficients and factors. This FEMA P695 study was conducted to substantiate the design coefficients and factors that should be used for such CC-PSW/CF structures. Read more
