The reinforced concrete structural wall is an important lateral load resisting element. It is increasingly used by designers in new structures as well the rehabilitation of existing ones. There are models that represent the flexural behaviour of walls to various degrees of accuracy.
Simple structural concrete members will be reinforced with steel. In this case the steel reinforcement provides the tensile strength, and the concrete provides the compressive strength. In this case the compressive strength of concrete is the defining strength parameter only because the concrete is not expected to provide any tensile strength ...

REINFORCED CONCRETE STRUCTURES Topic 11 is the seismic design of reinforced concrete structures, primarily buildings. During this lesson you will learn the basics of seismic design of reinforced concrete buildings. Buildings designed using these principles will fare better in a seismic event than the building shown in this slide.
Reinforced concrete (RC) structural walls are commonly used as the primary lateral-load resisting system for new construction and system rehabilitation in zones of moderate-to-high seismicity ...

The deformation of beam-column joints may contribute significantly to drift of reinforced concrete (RC) frames. In addition, failure may occur in the joints due to cumulative concrete crushing from applied beam and column moments, bond slip of embedded bars or shear failure as in the case of existing frames with nonductile detailing.

Reinforced concrete shear wall (RC wall) is an important element in tall buildings, which provides strength and stiffness against lateral loadings, e.g. earthquake and wind. Numerous researches have been conducted to study its nonlinear behavior via microscopic and macroscopic model. The later approach is currently being widely explored since it has many advantages compared to the preceding ...
In order to study the restoring force model of low-rise concrete shear wall with single layer of web reinforcement and inclined rebars, a series of specimens were investigated by quasi-static tests. Based on the fitting of experimental data and theoretical analysis, the restoring force model considering four characteristic points (crack point, yield point, peak point and failure point) and ...

6th U.S. National Conference on Earthquake Engineering Topic Index Author Index Main Menu Displacement Capacity The modes of failure that affect the ultimate behavior of structural walls are: boundary element crushing, bar fracture, inelastic bar buckling, instability of compressive concrete, web crushing, and sliding shear (Oesterle, 1985).
Concrete exhibits a complex structural response with various important nonlinearities; namely, a non- linear stressstrain behavior, tensile cracking and compression crushing material failures and tempera- ture-dependent creep strains [2-91, All these concrete nonlinearities depend strongly on the triaxial state of

The objective of the experiments is to determine ductility, energy dissipation capacity and strength of a wide variety of walls. Isolated walls representipg those found in structural wall systems were tested. Test specimens were approximately 1/3
Date: 5/1/1984. Abstract: Results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated. Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper.
This paper outlines an approach to assessing the horizontal shear capacity of hollow rectangular bridge piers designed to support 3 new toll bridges in the San Francisco Bay Area under seismic loads. The approach focuses on the piers capacity in diagonal compression, or their web crushing capacity, as it relates to the fanning crack pattern inside the plastic hinge region.
