Influence of Loading History on Delamination in Multilayered Beam with Creep Victor Iliev Rizov1,a* 1Department of Technical Mechanics, University of Architecture, Civil Engineering and Geodesy, 1 Chr.
Introduction Multilayered beam structures made of adhesively bonded layers of dissimilar materials are attracting significant attention mainly due increasing performance demands in up-to-date engineering applications.
Such materials are also used in engineering applications in aggressive environment.
However, the engineering practice shows that the fundamental disadvantage of multilayered materials and structures is the delamination fracture.

The early-age drying shrinkage of cement-based materials with the same workability after temperature compensation Lifeng Zhang1, a, Junying Lai1, b, Xiaoqian Qian1, c and Chong Shen1, d 1College of Civil Engineering and Architecture, Zhejiang University, Hangzhou 310058, china azhanglifeng@zju.edu.cn, bjunyinglai@zju.edu.cn, cqianxq1@zju.edu.cn, d71136446@qq.com Keywords: paste; concrete; early-age drying shrinkage; workability; superplasticizer; temperature compensation Abstract.
Introduction Practical engineering shows the shrinkage starting from initial setting times is an important reason for concrete cracks.
The curing is often neglected in the period from the initial setting time to the final setting time in practical engineering, when the cracks often appear.
At the same time, the use of SP in practical engineering causes much more shrinkage.
But there are few studies focusing on the shrinkage of concrete with the same workability, and mixtures with same workability but added different SPs are much closer to the actual engineering.

Introduction The T-welded constructions are widely used in various domains (transport, civil engineering, offshore …).
In the case of engineering consulting firm, to obtain a safe design of this structure, the reliability approach adopted is based on the method of "Stress-Resistance".

Effects of normal pressure on the clogging behavior of geotextile and gap-graded soil filtration systems Zhaoxia Tong1, a, Lun Chen2,b,Shaopeng Zhou1.c 1School of Transportation Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing 100191, China 2State Key Laboratory of Hydroscience and Engineering, Tsinghua University, Beijing 100084, China atongzx@buaa.edu.cn, blunchen@tsinghua.edu.cn, czhoushaopeng1987@163.com Key words: normal pressure; geotextile; gap-graded soil; filtration; clogging Abstract.
Introduction The use of geotextiles as filters instead of the traditional granular materials has become more and more popular in the seepage outlet and drainage inlet of the hydraulic, civil and environmental engineering.
For example, in the practical engineering, the normal pressure is usually applied on the geotextiles, and geotextiles may be subjected to the tension due to soil deformation.

The degree of accident risk associated with a complex engineering system, which is generally characterized by multiple hazards, is determined based on the analysis of aggregate indicators of risks identified during analysis of undesirable events (events related to equipment seal failure, adverse meteorological conditions).
