Performance-Based Design for a Shear Building Subject to Design Earthquakes with Non-Monotonic Displacement Spectrum by Using Time History Response Analysis

Abstract eng:
This paper proposes a stiffness design method for shear buildings subject to a design earthquake with a non-monotonic displacement spectrum. The objective function that is a combination of the fundamental natural period which represents 'cost' and the level of maximum displacements which represents 'performance' is introduced into the design method to find a set of story stiffnesses under response constraints. An inverse problem formulation is used to find the stiffness such that the shear building would exhibit maximum inter-story drifts proportional to specified ones. Several design examples and time history response analyses are performed to demonstrate the validity and the accuracy of the proposed design method.
