Stiffness For Linear Seismic Analysis Of Concrete Walls

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.

Stiffness for linear seismic analysis of concrete walls.

Effect of stiffness on the seismic performance of code conforming reinforced concrete shear wall buildings. The effective initial stiffness should account for cracking of the concrete and other phenomena that reduce. Such a stiffness is illustrated by the ei effective line in figure 1. 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. 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 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.
