Stiffness For Linear Seismic Analysis Of Concrete Walls

Test of high rise core wall.

Stiffness for linear seismic analysis of concrete walls.

Effect of stiffness on the seismic performance of code conforming reinforced concrete shear wall buildings. 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. 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. 5 appears on pages s.

Such a stiffness is illustrated by the ei effective line in figure 1. Effective stiffness for seismic analysis author s. A test was conducted on a large scale model of a concrete. 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.
