The seismic performance of elliptic braced moment resisting frame (ELBRF) is assessed here and is found that the structural behavior is improved and is of free of architectural space. The demand for seismic performance of ELBRF is estimated through conventional pushover methods of 3, 5, 7, and 10-story ELBRF frames and they are compared with special moment resisting frames (SMRF) and X-Braced C...

Finite-element models of varying sophistication may be employed to determine a building’s seismic response with increasing complexity, potentially offering higher fidelity at the cost computational load. To account for this effect on reliability performance assessment, model-type uncertainty needs incorporated as distinct related given model’s parameters. At present, only placeholder values are...

A case study of retrofitting a 20-story pre-Northridge steel moment-frame building is presented. Twelve retrofit 4 schemes are developed with varying degrees of intervention. Three retrofitting techniques are considered: up5 grading the brittle beam-to-column moment resisting connections, and implementing either conventional or 6 buckling-restrained brace elements within the existing moment-fra...

Diaphragms are a fundamental part of the earthquake-resistant system, and in terms rigidity, it is essential to transmit dynamic loads on base structure.Also, floor openings response buildings against progressive collapse issues that have received less attention.In this study, opening surfaces their positions potential steel moment-resisting frame (SMRF) were investigated according alternate lo...

Abstract This study presents the impact of near-field and far-field earthquakes on seismic design Intermediate Moment Resisting Frame (IMRF) Special (SMRF) structures through FEMA (Federal Emergency Management Agency) P695 methodology to highlight importance probabilistic collapse as well performance factors these structures. The purpose this is investigate steel intermediate special moment res...

The steel frame reinforced with steel shear wall is a lateral load resisting system and has higher strength and shear performance than the concrete shear wall system. Especially, using corrugated steel plates in these shear wall systems improves out-of-plane stiffness and flexibility in the deformation along the corrugation. In this paper, a cyclic loading test of this steel frame reinforced wi...
