A DPIM-based framework for reliability analysis of building structures under stochastic near-fault ground motions
ICASP14; Chen, Guohai; Yang, Dixiong (2023)Near-fault ground motions have the forward directivity effect and fling-step effect, both of which can produce the distinct long-period pulse in velocity time histories. Such velocity pulses with larger amplitude easily ... -
An efficient approach to reliability-based topology optimization of continuum structures with multimodal distributions
ICASP14; Lei, Zhenzeng; Yang, Dixiong (2023)Reliability-based topology optimization (RBTO) considering uncertainties has attracted great attention recently. In practical applications, some random variables follow multimodal distributions, thus, RBTO with multimodal ... -
Direct probability integral method-based system reliability sensitivity analysis and design optimization
ICASP14; Li, Hui; ; Chen, Guohai; Yang, Dixiong (2023)System reliability-based design optimization (SRBDO) can take an optimal trade-off between economy and safety in structural design with multiple failure modes, in which the evaluation of system reliability and its sensitivity ... -
Dynamic responses and flow field characteristic of stochastic Burgers equation
ICASP14; Wang, Junwen; Yang, Dixiong; Chen, Guohai (2023)Turbulent flow is a highly irregular motion which is usually described as stochastic process in engineering analysis and design, and Burgers equation as a turbulence model has been widely used in various fields. In order ... -
Random vibration and global dynamic analyses of nonlinear MDOF systems under combined additive and multiplicative excitation
Yang, Dixiong; Chen, Guohai; Chen, Hanshu; ICASP14 (2023)The random vibration and global dynamic analyses of structures subjected to combined additive and multiplicative excitation are challenging issues. In this paper, the direct probability integral method (DPIM), as a novel ... -
Stochastic responses analysis of vibro-impact system via direct probability integral method
Yang, Dixiong; Zhang, Yu; ICASP14 (2023)Vibro-impact system, as an important type of non-smooth system in mechanical engineering, has received much research interest in the past few decades. The behaviors of vibro-impact system are complex and unusual, because ... -
Unified framework of stochastic structural dynamics: direct probability integral method
ICASP14; Yang, Dixiong; Chen, Guohai (2023)Stochastic dynamics of structures involves the topics of simulation of random excitation, random vibration analysis, reliability estimation and reliability-based design optimization. However, the existing methods only focus ...
