Abstract: Current precast concrete diaphragm design may not necessarily protect the diaphragm from a nonductile shear failure in an overload situation. As evidence exists that diaphragms can attract large inertial loads during strong ...

Abstract: Precast spandrel beams are often used on the perimeter of precast buildings to support the precast floor units. These elements are typically not considered part of the lateral force resisting system. However, the presence ...

Abstract: Precast concrete diaphragm seismic response is examined in experimental research integrating model-based simulation with physical testing. The experimental substructure is the diaphragm critical flexural region of a prototype ...

Abstract: This paper summarizes key diaphragm response parameters observed during the shake table testing of a three-story precast concrete structure built at half-scale. The test structure geometry possessed an aspect ratio in plan ...
