Prediction on sound insulation to a single-leaf wall HUANG Xianfenga, YANG Zongxiaob and YANG Yanc Key Laboratory of Disaster Prevention and Structural Safety at Guangxi University, Ministry of Education & College of Civil Engineering and Architecture, Guangxi University, Nanning, China aseulee@163.com, byzx19880125@126.com, cyangyan657079499@126.com Keywords: Single-leaf wall; coincidence effect; sound insulation Abstract.
The difference between the prediction of this paper and the measured data is less than 3dB, which is an acceptable deviation in engineering practice.
This calculation method in this paper can predict coincidence effect of a single-leaf wall, meanwhile the difference between the predicted sound insulation and measured data agrees better than it used to be, and it is able to meet the requirement of the engineering practice.

Experimental Investigations for Compression-Flexure Characters of Laminated Box Beam Columns Yaping Wu 1, 2,a, Yuru Zhao 2,c, Jiawei Zhang 2,b, Yinhui Wang 1,d 1 Ningbo Institute of Technology, Zhejiang University, Ningbo 315100 China 2 School of Civil Engineering, Lanzhou Jiaotong University, Lanzhou 730070 China a yapingwu58@126.com, b zyru@126.com, c zhangjd@mail.lzjtu.cn, d wangyh7244@nit.zju.edu.cn Keyword: Experimental investigations, Compression-flexure characters, Laminated box beam column Abstract.
Introduction In the construction of bridges and architectural engineering structures, the thin-walled box beams are widely used [1-4].
With the features of high efficiency, low consumption and good mechanical characteristic, thin-walled composite box beams have been broadly adopted in structural engineering, and its mechanical behavior has became an active research area. [5-7].

Nonlinear buckling analysis of shallow spherical shell under uniform pressure and temperature field Zhu Yong An1,2,3 a, Wang Fan1,3 b 1Mechanics and civil engineering Department in Jinan University, China 2 Infrastructure Department in Jinan University, China 3 Institute of Applied Mechanics in Jinan University, China asenhong@163.com btwfan@jnu.edu.cn Keywords: shallow spherical shell; nonlinear buckling; modified iteration method; temperature field.
In this paper, nonlinear buckling of shallow spherical shell under uniform pressure and temperature field in simply supported boundary conditions is studied, which can provide reference to the engineering designing.
For the designing of engineering structure, the upper critical load is usually taken into account as the designing value.

In practical project, engineering accidents happen due to not familiar with concrete’s characters and strength criterions under tension condition.
) （） （） Take the engineering practicality into consideration, and the errors have little differences, select simple equation form as possible.

Numerical Analysis on Bending Deep Beams with Different Moduli in Tension and Compression Jun-yi Sun1,2a, Zhen-hong Cai1,2b, Zhou-lian Zheng1,2c, Xiao-ting He1,2d 1College of Civil Engineering, Chongqing University, Chongqing 400045, PR China 2Key Laboratory of New Technology for Construction of Cities in Mountain Area(Chongqing University), Ministry of Education, Chongqing 400045, PR China asun.junyi@yahoo.com.cn, bydlcqu@163.com, czhqcqu@163.com, dxiaotinghe@163.com Keywords: Bimodulus; Elastic moduli; Beams and Girders; Bending; Stresses; Deformation Abstract: Based on the numerically iterative technique, we introduce the shear modulus pattern used for accelerating convergence and rebuild the iterative program.
There are two bimodular material models widely used in theoretical analysis within the engineering profession.
The effect of different moduli in tension and compression will influence greatly the bending stress and deflection of elastic deep beam in bending, thus should be given the more attentions in the analysis and design of engineering structures.
