abstract for seismic design, it is important to estimate the, maximum lateral displacement (inelastic displacement) of the structures due to earthquakes for several reasons. seismic design provisions estimate the maximum roof and storey drifts occurring in major earthquakes by amplifying the roof displacement and drifts of the structures obtained by elastic analysis subjected to seismic design ...

In this study, the methodology recommended by FEMA P695 is employed to evaluate seismic performance of self-centered y-shaped (SCY) braced frames. To apply system interest, twenty archetype models are deigned. The collapse safety then evaluated through incremental dynamic analyses (IDA) and pushover analyses. results show that secondary stiffness length self-centering (SC) element key parameter...

The seismic response of non-structural components (NSCs) attached to irregular reinforced concrete (RC) multi-storey buildings is underestimated by current European design provisions. This paper presents a new model for NSCs, accounting the effect torsion and capacity an RC primary structure (P-structure). proposed modification Eurocode 8 (EC8) acceleration amplification factor NSCs. It based o...

in this paper the response modification factor due to ductility and saved strength of cylindrical concrete elevated and ground tanks is obtained using finite element method and nonlinear push over analysis considering the lateral effective modes of tanks. to modeling the behavior of the tank materials, the five parameters william-warnke and prefect elastoplastic models are used for concrete and...

This study aims to develop seismic fragility curves for a typical pile-supported wharf. Fragility curve is one of the popular tools in seismic performance evaluation of a structure. The software FLAC2D was used to simulate the seismic performance of the wharf structure. Using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (IDA) was applied for sei...

Increased monitoring of civil structures for response to earthquake motions is fundamental to reducing seismic risk. Seismic monitoring is difficult because typically only a few useful, intermediate to large earthquakes occur per decade near instrumented structures. Here, we demonstrate that the impulse response function (IRF) of a multistory building can be generated from ambient noise. Estima...

Although, experimental studies have reported fracture at the corner of Steel Plate Shear Walls (SPSW), no study has been performed to investigate the crack effect, yet. Therefore, in this paper, the effect of crack at the corner of SPSWs on the seismic behavior of the system was investigated. Two probable cracks, that have been studies at the corner of SPSWs utilizing extended Finite Element me...

A conceptual framework for the probabilistic performance-based seismic assessment of building structures that considers both model uncertainty and response sensitivity to ground motion modification is presented in this paper. A new damage model is proposed for the assessment of building performance to seismic loads. The model is derived at the material level and combined at the element, story a...

The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab. Steel brackets are used as foundation and floor connections. Experimental cycl...

This paper’s main aim was to explain the process of characterising structural over-strength factor (R), seismic behaviour (Q), and effective elastic stiffness, Keff, cantilever-reinforced concrete (RC) urban bridge columns with solid circular cross-sections for use in design under Serviceability Limit State (SLS). Similarly, mathematical models have been proposed determine average values stiffn...
