Performance Based Seismic Design

Linked column frame system, as a new seismic load-resisting system, has a proper seismic behavior in various performance objectives due to ductile behavior of replaceable link beams. Thus, returning to occupancy after moderate earthquake is rapid and low-cost. Performance-based seismic design methods should be used for this system in order to have proper seismic behavior. In this study, by using performance-based plastic design method, a highly accurate and simple design procedure is proposed for this system. 9 prototype structures with 3, 6 or 9 stories and with 3, 4 or 5 bays are selected for parametric design and assessment. For assessment of the designed structures, nonlinear static and dynamic analyses with models according to experimental test results of the members and recommended ground motion records of FEMA P695 are used. According to analyses results, the designed structures in three hazard levels meet the performance objectives.

This paper presents a direct displacement design (DDD) procedure that can be used for seismic design of multistory wood-framed structures. The proposed procedure is applicable to any pure shear deforming system. The design procedure is a promising design tool for performance-based seismic design since it allows consideration of multiple performance objectives (e.g., damage limitation, safety requirements) without requiring the engineer to perform a complex finite element or nonlinear time-history analysis of the complete structure. A simple procedure based on normalized modal analysis is used to convert the code-specified acceleration response spectrum into a set of interstory drift spectra. These spectra can be used to determine the minimum stiffness required for each floor based on the drift limit requirements. Specific shear walls can then be directly selected from a database of backbone curves. The procedure is illustrated on the design of two three-story ATC-63 archetype buildings, and the results are validated using nonlinear time-history analysis.

Performance Based Seismic Design

In the present work, a Performance-Based Seismic Design procedure applied to multi-storey frame structures with innovative hysteretic diagonal steel devices (called Crescent Shaped Braces or CSB) is introduced. CSBs are steel elements of peculiar geometrical shapes that can be adopted in frame buildings as enhanced hysteretic diagonal braces. Based on their "boomerang" configuration and placement inside the frame structure, they are characterized by a lateral stiffness uncoupled from the yield strength and, if properly inserted, by an overall symmetric hysteretic behavior with hardening response at large drifts, thus preventing from global structural instability due to second-order effects. The procedure here presented is intended to guide the structural engineer through all the steps of the design process, from the selection of the performance objectives to the preliminary sizing of the CSB devices, up to the final design configuration. The steps are described in detail through the development of an applicative example.
