RISAccurate Application and Second-Order Improvement of SAC/FEMA Probabilistic Formats for Seismic Performance Assessment<sup>1</sup>
Publisher: American Society of Civil Engineers
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, ...
Seismic Performance Uncertainty Estimation via IDA with Progressive Accelerogram-Wise Latin Hypercube Sampling
Publisher: American Society of Civil Engineers
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 ...
Model Type Effects on the Estimated Seismic Response of a 20-Story Steel Moment Resisting Frame
Publisher: ASCE
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 ...
Stability of Single-Bolted Thin-Walled Steel Angle Members with Stochastic Imperfections
Publisher: ASCE
Abstract: The focus of this paper is on the probabilistic estimation of the buckling capacity of single-bolted members from plain or lipped angle sections with stochastic geometric imperfections. A joint experimental-stochastic ...
Simplified Modeling for the Seismic Performance Assessment of Automated Rack-Supported Warehouses
Publisher: ASCE
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 ...
Seismic and Vibration Performance Rehabilitation for an Industrial Steel Building
Publisher: ASCE
Abstract: A rehabilitation plan is presented for a two-story industrial steel structure in Iran. The building was found to have unsatisfactory performance: The first-floor two-way composite slab was prone to uncontrollable vibrations ...
Direct Estimation of Seismic Demand and Capacity of Multidegree-of-Freedom Systems through Incremental Dynamic Analysis of Single Degree of Freedom Approximation1
Publisher: American Society of Civil Engineers
Abstract: Introducing a fast and accurate method to estimate the seismic demand and capacity of first-mode-dominated multidegree-of-freedom systems in regions ranging from near-elastic to global collapse. This is made possible by ...
Surrogate Modeling for the Seismic Performance Assessment of Liquid Storage Tanks
Publisher: American Society of Civil Engineers
Abstract: A three-dimensional surrogate model is presented for the seismic performance assessment of cylindrical atmospheric liquid storage tanks. The proposed model consists of a concentrated fluid mass attached to a single vertical ...
Performance-Based Seismic Design: Avant-Garde and Code-Compatible Approaches
Publisher: American Society of Civil Engineers
Abstract: Current force-based codes for the seismic design of structures use design spectra and system-specific behavior factors to satisfy one or two predefined structural limit states . In contrast, performance-based seismic design ...
