Seismic analysis of soil-structure interaction (SSI) is a challenge due to the nonlinearities of soil-foundation interaction (SFI). The reliability of the design and the analysis results will suffer if SSI is ignored. In this paper, a two-step method based on the superposition theorem is used to perform a seismic analysis of a soil-foundation-tank-liquid system (soil-liquid tank system).

A new formulation to calculate the shakedown limit load of Kirchhoff plates under stochastic conditions of strength is developed. Direct structural reliability design by chance constrained programming is based on the prescribed failure probabilities, which is an effective approach of stochastic programming if it can be formulated as an equivalent deterministic optimization problem.

In globalization, the selection of the specifications for design practices depends on the investment agency. For example, steel truss structures can be designed using various codes, such as AISC 360-16 or EC 3. Although most specifications have recently been written in the limit state design approaches, which codes resulting in reasonable design solutions are rarely investigated.

This work aims at investigating the effect of aleatoric uncertainty of creep rock properties on the stability of an underground structure. This uncertainty relates to the spatial variability of the mechanical parameters representing the time-dependent behavior of geological rock formation due to the change in its mineralogy.

The probabilistic analyses provide a more rational approach for the safety assessment of structures since they consider the uncertainties in the calculations. This study employs the fully probabilistic analysis as an additional analysis to examine the reliability index of an LRFD-based design of the truss structure.

The study aims to investigate the factors affecting marketing strategy of logistics enterprises in the central key economic region. This study uses quantitative research methods through SPSS to test the scale reliability, exploratory factor analysis (EFA) and regression analysis. Data were collected from 120 logistics enterprises in the central key economic region. The results show that four factors positively affect the marketing strategy of logistics enterprises, including information technology capability, human resources, competitors, legal environment.

In this study, we used the reliable GC-FID/MS technique to analyze the methyl ester derivatives of 37 different kinds of fatty acids. The results showed that high saturated fat concentration in all samples was mostly palmitic acid, whereas the low unsaturated fatty acid content in the cis form was primarily oleic acid and linoleic acid. The amount of monounsaturated and polyunsaturated fats is quite low.

The dynamic analysis is a necessity in the design, manufacturing and maintenance of structures. The analytic solutions are not available for most practical cases and the Finite Element Method (FEM) is not reliable due to the joint problem, unclear loading, material properties and numerical error. In this paper, we present a way to find modes shape of 3D Frame by FEM program using Matlab.

The aim of this research is to improve the reliability of the dynamic formula. This research program will concentrate on the proposal of a correction factor to adjust for this dynamic component similar to the damping parameter used in the Wave Equation Analysis and validate its reliability experimentally and theoretically. Similarly, the issue of the variation in the hammer energy delivered to pile needs to be improved by the adoption of new technology and validate experimentally.
