Abstract: A new general variational theorem is proposed for the analysis of elastoplastic solids. By utilizing the method of Lagrangian multipliers, a Hellinger/Reissner-type theorem is derived wherein the ...

Abstract: The SEAONC/ATC/CUREE (SAC/FEMA) probabilistic framework is based on a closed-form expression to estimate analytically the value of the risk integral convolving seismic hazard and structural response. Despite its practicality, ...

Abstract: An algorithm is proposed for the rapid estimation of the influence of model parameter uncertainties on the seismic performance of structures using incremental dynamic analysis (IDA) and Monte Carlo simulation with Latin ...

Abstract: A reduced-order modeling approach is proposed for the linear and nonlinear analysis of automated rack-supported warehouse (ARSW) structures under seismic loads. Steel ARSWs are massive structures that employ traditional ...

Abstract: This paper presents fragility functions to estimate the probability of reaching or exceeding different damage states in reduced beam section (RBS) beam-to-column moment connections of steel moment resisting frames. The ...

Abstract: Laminated elastomeric bearings are used widely as seismic isolation devices. Most previous studies on the horizontal behavior of elastomeric bearings have assumed that the rotations of the top and bottom supports of the ...

Abstract: Finite-element models of varying sophistication may be employed to determine a building’s seismic response with increasing complexity, potentially offering a higher fidelity at the cost of the computational load. To account ...
