Deep Deck and Cellular Deck Diaphragm Strength and Stiffness Evaluation
Twenty cantilever diaphragm tests were performed in the Structures and Materials Laboratory at Virginia Tech. The tests included both deep deck and cellular deck profiles with varying structural and side-lap connections. The tests were conducted with three different structural connections: screws, …

Analytical investigation of composite diaphragms strength and behavior
Composite diaphragm strength and behavior were studied using non-linear finite element analysis. A total of 57 three panel diaphragm models were analyzed to failure. Parameters studied included beam size and orientation, panel dimension, connector type and distance, slab opening, yield plateau, and …

Experimental and Analytical Evaluation of FRP-Retrofitted Reinforced Concrete Diaphragms for In-Plane Shear Strengthening
Diaphragms are a key component of the horizontal lateral force resisting system (hLFRS) in a reinforced concrete (RC) structure and are crucial for providing sufficient load path to the vertical lateral force resisting system (vLFRS). Diaphragms may require retrofit due to the relocation of vLFRS …

Experimental Program for Fiber Reinforced Polymer Retrofit of Reinforced Concrete Diaphragms
… horizontal loads are trans-mitted from the floor diaphragms to the columns and walls that comprise the vertical lateral force resisting system in a building. Strengthening of the diaphragms in older reinforced concrete buildings may be necessary for several reasons, including to enhance seismic …

Analysis and Design of Fiber Reinforced Polymer Retrofit of Reinforced Concrete Diaphragms
… horizontal, vertical, and foundation components. Diaphragms form the horizontal LFRS, transmitting lateral loads from earthquakes and wind events to vertical systems such as moment frames and shear walls. In reinforced concrete (RC) buildings, diaphragms often require retrofit due to …
