Steel bracing members are widely used in steel structures to reduce lateral displacement and dissipate energy during earthquake motions. Concentric steel bracing provide an excellent approach for strengthening and stiffening steel buildings. Using these braces the designer can hardly adjust the stiffness together with ductility as needed because of buckling of braces in compression. In this stu...

Open Ground Storey buildings (OGS) are commonly constructed in the UAE, since these has some functional advantage as parking, shop etc. However, they can be a hazard during an earthquake. In this study, real building located Al Muraqqabatm Dubai is chosen. This type of OGS coupled with shearwall. To understand behaviour and strength non-linear Static Analysis (Pushover Analysis) carried out to ...

The primary focus of this study is to evaluate the nonlinear response reinforced concrete (RC) frames with two types brick infills viz., unreinforced masonry infill (URM) and semi-interlocked (SIM) together lintel beams, subjected seismic loads. quantified in terms reduction factor base shear. Infill walls are modeled using double strut cyclic element. Nonlinear static adaptive pushover analysi...

Abstract In this essay, the progressive collapse resistance of reinforced concrete wall-frame structures was evaluated with and without considering soil–structure interaction. The vulnerability frames against investigated middle column removal scenario from first story, based on sensitivity index. To evaluate effects interaction, along soil (hard soil) foundation were simultaneously modeled in ...

Numerical simulations have been widely used to study the inelastic response of reinforced concrete structures under earthquake loading. Yet, due to the complex nature of structural inelastic behavior, experimental results are often required to verify the efficiency of applied numerical schemes. In this paper, experimental results of bare reinforced concrete frame models are employed to validate...

This paper aims to guide structural engineers on how apply the rapid nonlinear time history analysis (RNLTHA) procedure effectively predict seismic demand, taking into account ductility and overstrength, effects of dynamic phenomena including cyclic degradation strength stiffness in structures, a direct expedient manner. The shortcoming conventional force-based approach design involving use for...

Abstract Existing reinforced concrete structures designed according to previous generation seismic codes, often suffer from premature, abrupt and detrimental failures in cases of intense earthquakes. In this study the response an existing building is analytically investigated while taking into account influence different detailing brick wall infills. The assessment performed with 3D static inel...
