semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. in this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (mr) damper has been studied for co...

Earthquake events have shown that besides the earthquake forces, interaction between fault rupture and structures could cause a lot of damage. Field observations revealed need to design for fault-induced loading in regions with active faults. In this study, three-dimensional numerical simulation was carried out evaluate performance 20-story frame building subjected propagation normal rupture. A...

The inter-story drift ratio (IDR) is a crucial parameter in structural health monitoring to judge the safety, stability, and serviceability of buildings. Real-time, continuous, widely applicable detection on IDRs essential. However, current methods present some challenges conducting such detection, including adverse effects from weather, requirement for large amounts space, fragile instruments....

The experience of past prominent earthquakes establishes the fact that the structure’s catastrophes and casualties can be dramatically decreased through the use of self-centering systems. A promising post-tensioned self-centering yielding braced system (PT-SCYBS) has been developed, comprising of two main components, including the post-tensioned wires, exhibiting the desirable self-centering pr...

This paper proposes a methodology framework for the reliability assessment of smart steel Moment Resisting Frame structures (MRFs) equipped with Nickle Titanium Shape Memory Alloy (NiTi SMA) connections subjected to blast loading. The is formulated based on two-step approach algorithm. In 1st Step, Monte Carlo Latin Hypercube Sampling Strategy simulation (MC-LHS) adapted generate uncertain para...

over the past decade of extensive research works, the thin un-stiffened steel plate shear wall(spsw) has now emerged as a promising lateral load resisting system. considering thedemand of performance-based seismic design (pbsd) philosophy in current and futureseismic design codes, a ductility-based design was recently proposed for spsw systems withpin-connected boundary beams. however, the effe...

The isolation technique is widely studied and applied in structural engineering due to its excellent seismic performance. However, the existing research mostly focuses on conventional structure under action of regular ground motions. In this paper, a story-adding structure, base-isolated isolated were simulated by using numerical simulation methods. dynamic response characteristics three struct...
