Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...

A full scale slice of a 7 story reinforced concrete building was tested on the shake table at the UCSD Engelkirk Structural Research Centre in 2006. As part of the research project, a blind prediction contest was sponsored to assess the capability of currently available analysis procedures to predict the seismic response of cantilever reinforced concrete shear wall structures. This paper descri...

Reinforced concrete walls are commonly used as the primary lateral-force-resistingsystem for tall buildings. As the tools for conducting nonlinear response history analysis have improved and with the advent of performance-based seismic design, reinforced concrete walls and core walls are often employed as the only lateral-force-resisting-system. Proper modeling of the load versus deformation be...

A reinforced concrete member in which the total span or shear span is especially small in relation to its depth is called a deep beam. In this study, a new approach based on the Adaptive Neural Fuzzy Inference System (ANFIS) is used to predict the shear strength of reinforced concrete (RC) deep beams. A constitutive relationship was obtained correlating the ultimate load with seven mechanical a...

This paper discusses the nonlinear dynamic seismic response of a 14-story reinforced concrete core wall building designed with prescriptive requirements 2019 California Building Code for near-fault site in Los Angeles, California, simulated detailed analysis complete structure and subjected to an ensemble three-component ground motion input. The study follows up on recently published work by au...

By Timothy Phillips Vaughan, MS. Washington State University May 2010 Chair: David I. McLean This research evaluated the structural performance of reinforced masonry shear walls conforming to requirements given in the 2008 MSJC Building Code Requirements for Masonry Structures under cyclic lateral loading. Seismic design provisions in the 2008 MSJC provide prescriptive requirements for three di...

Reinforced concrete walls are commonly used as the primary lateral force-resisting system for tall buildings. As the tools for conducting nonlinear response history analysis have improved and with the advent of performancebased seismic design, reinforced concrete walls and core walls are often employed as the only lateral forceresisting system.

The spacing of streaks of low-speed fluid has been studied experimentally in a wall-bounded turbulent flow in which sinusoidal unsteadiness was superposed on an otherwise steady mainstream over a range of frequencies. The modulation of phase-conditioned streak spacing about its mean value does not follow the steady wall-flow relation of hu Av equal to a constant. Instead, it is quite accurately...
