A methodology of data-driven damage state quantification with a probability estimation for structural hysteresis RC columns is presented in this paper. The knowledge learned from large-volume behavior database fully considered developing monitoring-oriented indicators, the established relationship between prediction and physics-based evaluation. In present study, 1015 different design parameter...

To study the strengthening effect of carbon fiber composite materials (CFRP) on recycled concrete columns subjected to different levels seismic damage, four column specimens were designed for pseudo-static tests. The categorized as non-destructive without (prototype), strengthening, medium damage and severe based replacement rate aggregates level damage. characteristics deformation performance ...

This paper presents a finite element (FE) analysis for predicting the flexural behavior of reinforced concrete (RC) beams strengthened with Fe-based shape memory alloy (Fe-SMA) strips using near surface mounted (NSM) method. Experimental results reported in literature were used to verify proposed FE model. analyses conducted OpenSees, general-purpose structural program. The RC beam specimens mo...

To improve the seismic performance of bridges, this study develops a novel superelastic conical friction pendulum isolator (SCFPI) by incorporating an improved (CFPI) with shape memory alloy (SMA). The flat sliding function designed for is to enhance adaptability under service loadings. analytical model SCFPI derived and numerical developed within OpenSees platform investigate hysteretic behavi...

In the process of vigorously promoting development China’s smart city construction site engineering, wide application BIM technology and its advantages have been widely reflected in various places such as remote video monitoring, visual chemical field technical data disclosure, statistical engineering volume. can effectively help enterprises manage whole site, significantly improve safety manag...

In recent decades, the considerable number of worldwide earthquakes caused damage and several building collapses, underlining high vulnerability existing buildings designed without seismic provisions. this regard, work analyses performance a reinforced concrete any criteria, characterized by seismically-stronger seismically-weaker direction, such as concrete-framed structures for vertical load ...

This paper is concerned with the seismic behavior of a superimposed slab shear wall. Based on test results specimens under low cyclic reversal loading, formulas respect to top displacement and capacity wall in consecutive loading process are derived. The concrete grade differentiation between prefabricated layer cast-in-site considered improve calculating precision. With help these equations, e...

To study the effects of infill wall on progressive collapse resistance reinforced concrete (RC) frames with slabs, a macro finite element (FE) model was built using general purpose software OpenSees. The FE validated by existing test results. Then, subsequently used to predict potential eight-story RC frame including slabs and walls. numerical studies demonstrated that inclusion walls could inc...
