Introduction Several engineering structures such as railways and pipelines rest on elastic foundations where the resulting time-dependent stresses due to the moving loads are much greater than those in the corresponding static cases.

Experimental study on flexural behaviors of steel reinforced recycled coarse aggregate concrete beams Wen-yue Qin 1, a, Yu-liang Chen 1, b, Zong-ping Chen 1, c, * 1College of Civil Engineering and Architecture, Guangxi University, Nanning 530004, China aqwy1025@163.com,bylchen616@163.com, c,*Corresponding Author:zpchen@gxu.edu.cn Keywords: recycled coarse aggregate, steel reinforced recycled concrete, flexural behaviors, experimental study Abstract: In order to reveal the flexural behavior of normal section of steel reinforced recycled coarse aggregate concrete beams，6 steel reinforced recycled concrete beams were designed for flexural test，the study mainly considered the impact of coarse aggregate replacement rates and concrete strength grade two changing parameters on the flexural behavior of steel reinforced recycled coarse aggregate concrete beams.
Steel reinforced concrete structure (SRC) has been developed over recent decades, and the benefits of using SRC structures include high bearing capacity, rigidity, and short construction period and so on, which make it widely used in engineering practice.
In the end, based on experimental provide useful reference data for further research and engineering practice.

Introduction Polymeric materials have already been used for several years but recently are present in nearly every branch of civil engineering due to their specific properties.
Considering the mathematics – such result is correct but considering the technical properties – it is necessary to find the extremum that would be correct and rational in an “engineering” sense.

Model Experimental Study on Stratified Air Distribution with 2D-PIV for High Ceiling Industrial Plant Jian Shen1,a, Angui Li1,b, Yujiao Zhao 1,c 1School of Environmental and Municipal Engineering, Xi’an University of Architecture and Technology, Xi’an, P.R.
Introduction Nowadays, high ceiling buildings have been appeared increasingly in the industrial and civil occasions.
With reference to the previous studies [1] and in consideration of PIV condition, we finally decide that the model size is 1/50 of the real one based on engineering experiences of past years.
Experimental facility layout Engineering models are usually used to study complex fluid dynamics problems where calculations and computer simulations are not reliable.
