Stiffness for linear seismic analysis of concrete walls.

A trilinear bending moment curvature model is used to develop a general method for determining the effective flexural stiffness of concrete walls for use in linear seismic analysis. Ibrahim and michael bryson publication. There is a wide variety of models that have been used to simulate the non linear behavior of reinforced concrete walls. Thus the appropriate stiffness for linear seismic analysis is an effective initial stiffness of the structure as it reaches the limit of essentially linear behavior.

5 appears on pages s. Test of high rise core wall. A trilinear bending moment curvature model is used to develop a general method for determining the effective flexural stiffness of concrete walls for use in linear seismic analysis. The effective initial stiffness should account for cracking of the concrete and other phenomena that reduce.

A test was conducted on a large scale model of a concrete. Effect of stiffness on the seismic performance of code conforming reinforced concrete shear wall buildings. Kausela statistical analysis of reinforced concrete wall buildings damaged during the 2010 chile earthquake. The method accounts for the initial section stiffness e c i g prior to cracking and the retention of initial stiffness after cracking due to axial compression.

Such a stiffness is illustrated by the ei effective line in figure 1.
