Performance Based Seismic Rehabilitation of Steel Structures with Different Types of Shear Walls
(Semnan University, 2019-11-01)Seismic rehabilitation provides existing buildings with more resistance to seismic activity, ground motion, or geotechnical failure due to earthquakes. Performance-based rehabilitation is a general concept through which ...

Effect of Degradation on Collapse Margin Ratio of Steel Moment Frames
(Semnan University, 2019-11-01)Although several studies have investigated the effect of degradation on the behavior of structures, investigations on collapse margin ratios are rare in the literature. In this study, the effect of strength and stiffness ...

Selection of Optimal Intensity Measure for Seismic Assessment of Steel Buckling Restrained Braced Frames under Near-Fault Ground Motions
(Semnan University, 2019-11-01)Buckling restrained braces (BRBs) have a similar behavior under compression and tension loadings. Therefore, they can be applied as a favorable lateral load resisting system for structures. In the performance-based earthquake ...

Investigation of the Distribution of Cumulative Ductility Demand Parameter in Various Stories of Buckling Restrained Braced Frames
(Semnan University, 2019-11-01)Due to the fact that the buckling-restrained brace core yields both in tension and compression, it can absorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important ...

Experimental Strengthening of the Two-way Reinforced Concrete Slabs with High Performance Fiber Reinforced Cement Composites (HPFRCC) Prefabricated Sheets
(Semnan University, 2019-11-01)Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical ...

Seismic Evaluation of Flexible-Base Low-Rise Steel Frames Using Beam-On-Nonlinear-Winkler-Foundation Modeling of Shallow Footings
(Semnan University, 2019-11-01)Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) can be detrimental to the seismic behavior of structure, and hence ignoring this phenomenon in analysis and design may result in to ...

Comparison of Progressive Collapse Capacity of Steel Moment Resisting Frames and Dual Systems with Buckling Retrained Braces
(Semnan University, 2019-11-01)Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential ...
