Equivalent Linearization for Hysteretic Systems Under Random Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of equivalent linearization for smooth hysteretic systems under random excitation is proposed. The hysteretic restoring force is modeled by a nonlinear differential equation and the ...
Methods of Random Vibration for Inelastic Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structures often become nonlinear and inelastic under severe lateral force produced by natural hazards such as earthquakes, severe winds and waves. The restoring force of the structures under ...
Approximate Methods for Nonlinear Time‐Variant Reliability Analysis
Publisher: American Society of Civil Engineers
Abstract: Exact solution of reliability of structures under stochastic loadings is generally difficult. Various approximate methods have been developed based on an outcrossing rate analysis. Several first‐order and second‐order ...
Description and Simulation of Nonstationary Processes Based on Hilbert Spectra
Publisher: American Society of Civil Engineers
Abstract: A new method is proposed for the description and simulation of nonstationary random processes based on Hilbert spectra of their sample observations. A sample of a random process is first decomposed into intrinsic mode ...
Stochastic Combination of Load Effects
Publisher: American Society of Civil Engineers
Abstract: The problem of evaluating the probability that a structure becomes unsafe under a combination of loads over a given time period is addressed. The loads and load effects are modeled as either pulse (static problem) or ...
Method of Reliability-Based Seismic Design. II: Calibration of Code Parameters
Publisher: American Society of Civil Engineers
Abstract: This is the second part of a two-part investigation on the method of a reliability-based seismic design. To account for large uncertainties in structural design under seismic load, a method of calibration of the design ...
Method of Reliability-Based Seismic Design. I: Equivalent Nonlinear Systems
Publisher: American Society of Civil Engineers
Abstract: This is the first part of a two-part investigation on the method of reliability-based seismic design. In reliability analysis and reliability-based design under stochastic loads such as seismic excitations, repeated ...
Minimum Building Life-Cycle Cost Design Criteria. I: Methodology
Publisher: American Society of Civil Engineers
Abstract: In view of the large damage suffered in recent earthquakes and hurricanes, building design criteria are developed to protect life and reduce damage and loss to an acceptable level. The problem is minimizing the expected ...
Structural Reliability/Redundancy under Earthquakes
Publisher: American Society of Civil Engineers
Abstract: Structural reliability/redundancy has become a serious concern in the building industry after the poor performance of some buildings in recent earthquakes. Yet, there is a general lack of thorough understanding of structural ...
Design Live Loads for Passenger Cars Parking Garages
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to obtain a better understanding of live loads in passenger cars parking garages and to recommend an appropriate value for design. Load surveys were conducted in nine parking garages in Chicago ...
