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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
