Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...

in this paper, acceptance criteria of steel building code, comprehensive and quick evaluation procedures for x-bracing, are compared to each other parametrically and numerically. for this purpose, it is assumed first that the sample building is designed to meet steel building code and then by introducing transform parameters and using stress ratio of the designed components, acceptance of the d...

conventional methods for seismic design of structures are based on building capacity. because of the disadvantages of conventional methods, base isolation system  is known as an effective solution to protect structures against earthquakes. in this study the operation of 2-storey steel frame with and without seismic isolators under near-fault earthquake of chichi، northridge and  capemendocine  ...

This paper focuses on understanding and assessing the effect of hysteretic behavior (i.e., bilinear, peakoriented and pinching) in the evaluation of peak deformation demands and their distribution over the height for regular frame structures over a wide range of stories (from 3 to 18) and fundamental periods (from 0.3 s. to 3.6 s.). The ground motions used are those with frequency content chara...

Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD go...

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...

Abstract. The equivalent linearization program LSSRLI-1, proposed by Xiaojun Li in 1989, is the important content in seismic zoning work and seismic safety evaluation of engineering sites. It is necessary to check the applicability of LSSRLI-1 to all kinds of sites. The mainly elaboration of this paper is verifying the applicability of seismic safety evaluation program LSSRLI-1 in stiff and hal...

fragility curves represent the probabilities that structural damages, under various levels of seismic excitation, will exceed the specified damage states by means of earthquake intensity damage relations. conceptual aspects related to seismic vulnerability, damage and risk evaluation are discussed first, together with a short review of the most widely used possibilities for the seismic evaluati...
