Seismic performance of single-propped retaining walls
… FLAC v7.0 (Itasca). The structure comprises two reinforced concrete diaphragm walls connected by a row of cross-lot struts that is used to support a 9.5m deep, 18m wide excavation in dry sand. After simulating the excavation as a staged construction, a suite of thirty-two (32) different seismic …

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 …

Ground movements due to excavation in clay: physical and analytical models
… of wall stiffness between sheet-piles and thick diaphragm walls. Wall stiffness was found to have a negligible influence on the magnitude of the wall bulging displacements for deep excavation supported by fixed-based wall with stiffness ranging from sheet pile walls to ordinary reinforced …

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 …
