Abstract null null Calculation of probability of exceedance for nonstationary non-Gaussian responses remains a great challenge to researchers in the field of structural reliability. In this paper, an analytical solution is proposed for calculating the mean upcrossing rate (MCR) of the non-stationary non-Gaussian responses by approximating the displacement and velocity responses with the bivariate vector translation process, in which the unified Hermite polynomial model (UHPM) is selected as the ...

Abstract Passive building technology belongs to the near-zero-energy building technology system, which maximizes the utilization of free energy from the ambient environment to reduce building energy consumption. In recent years, it has been widely recognized and developed rapidly. This paper takes a lot of effort to review the advances in the research and development of passive buildings in China, including the development status, representative projects and emerging technologies, design tools, ...

Abstract This study performed design optimization on a building with integrated photovoltaic, Trombe wall and phase change material based on building life cycle cost (LCC) and indoor thermal comfort. A total of thirty-four design variables were considered as the optimization variables. The optimization process consists of four steps. Firstly, Monte Carlo Method was used to generate a set of design samples, and the LCC and indoor discomfort degree hour were obtained through computer simulation. S...

Abstract Buried pipes, as a significant civil infrastructure, play a vital role in water, oil and gas transports. In this paper, a systematic method is developed to accurately predict the failure probability of a buried pipeline network at various levels of failure mode, pipe segment and whole pipeline system. A framework of system reliability is proposed to integrate the ultimate and serviceability failures. The random field theory is employed to model the distribution of corrosion, considering...

Abstract Methods to establish the fracture resistance curves for ductile materials have been standardised only for mode-I fracture tests. However, the failures of engineering structures can be caused by various loading modes due to the complex loading conditions or inclined crack-like flaws. This paper develops a new method to construct the fracture resistance curves for ductile steels under different in-plane loadings, based on the digital image correlation technique. Fracture tests are conduct...

This paper presents the results produced from long-term tests designed to investigate the key factors affecting the external corrosion of cast iron pipes buried in clayey soil. The coupled effect of varying acidity (pH) and saturation (moisture content) of soil on the corrosion of cast iron buried in soil, including pitting corrosion, is thoroughly examined. Based on the observations and analysis of the test results, it is found that the coupled effect of high acidity (2.5 pH) and high saturatio...

Abstract In this paper, the combined effect of corrosion and fatigue on the fatigue strength of steel connection plates is thoroughly investigated through a comprehensive experimental program. A model for fatigue strength degradation as a function of corrosion rate is developed. The mechanism of fatigue strength degradation is also examined to gain a insightful understanding of fatigue strength degradation under simultaneous corrosion and fatigue environments. It is found in the paper that the s...

Unloading compliance (UC) method and normalization method (NM) are two of the most commonly used methods for determining the fracture toughness of materials. However, considerable differences often exist in the fracture toughness determined by these two methods, which solicits a new method to determine the fracture toughness accurately. In this paper, the compliance of crack length differences as measured by the crack length difference ratio Si is discovered, analysed and verified by experiments...

Abstract This study presents a new dual time-variant chloride diffusion model considering maximum phenomenon for concrete structures exposed to marine environment. The model is developed from the assumption that the concentration gradient is the sole or dominant driving force for chloride ingress in concrete, and both the chloride diffusion coefficient and peak chloride content are considered as time-variant. The applicability and accuracy of the developed model are verified by comparing the fit...
