Stiffness for linear seismic analysis of concrete walls.

Effect of stiffness on the seismic performance of code conforming reinforced concrete shear wall buildings. 5 appears on pages s. 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. Guidance for effective stiffness modeling of shear walls in codes standards and references while fairly clear as they apply to wind analysis lack clarity and consistency when it comes to seismic analysis applications.

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. Walls when used with the accompanying impacts on construction costs available rentable space and non structural components. Kausela statistical analysis of reinforced concrete wall buildings damaged during the 2010 chile earthquake. There is a wide variety of models that have been used to simulate the non linear behavior of reinforced concrete walls.

Effective stiffness for seismic analysis author s. Test of high rise core wall. A test was conducted on a large scale model of a concrete. Ibrahim and michael bryson publication.

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.
