The Absolute Torsion of Circular Shaft and Neutral Cross-section Qiang LUO1,a,Liang-bin Qin 1,b 1.College of Civil and Architectural Engineering, Panzhihua University, Panzhihua 617000,CHINA aLuoqiang8125@163.com , b277466201@qq.com Key words: Circular shaft; torsion; relative torsion angle; neutral cross-section; absolute torsion angle Abstract: Mechanics of materials are based on the relative deformation to discuss the calculation of the circular shaft torsion deformation, But the relative torsion angle can not reflect the real deformation of a specific cross-section.
According to the plane hypothesis, to discuss the absolute deformation of several common shaft withstand the simple torque, defined the neutral cross-section of torsion deformation and given the method to calculate absolute torsion angle, for the rational design of engineering components have a certain reference value.
In order to rational design of engineering structure, the absolute torsional deformation should be calculated.
Neutral cross-section and calculate the absolute torsion angle for the rational design of engineering structures also have some reference value, if turning, drilling, milling, planing, etc. mounted on a neutral cross-section, can greatly improve the machining accuracy.

Design and field test of bolt-mesh-cable support of extraction drift in soft thick seam with a large angle Guo Dongming1,2,a, Zhuang Jingzhao3*,b, Zhang Yi1,2,c ,Wang Yanbin2,d , Yang Renshu1,2,e 1State Key Laboratory for Geomechanics & Deep Underground Engineering, Beijing,100083, China 2School of Mechanics & Civil Engineering, China University of Mining and Technology, Beijing, 100083, China 3Dept. of Civil Engineering, China Agricultural University, Beijing, 100083, China awjgdm1999@163.com, bzjzhao@cumtb.edu.cn, csongshu0209@126.com, d675080560@qq.com, edmguo@cumtb.edu.cn Key words: large angle, soft thick seam, bolt-mesh-cable support, simulation, ground pressure monitoring Abstract.
Considering the poor support results of extraction drift in soft thick seam with a large angle in Dujiacun Mine, and there’s no similar design in such engineering geological conditions.
Bolt as a good entry in mining support means the application of the gently inclined seam very successful [3-4], but the big dip "three soft" thick seam mining tunnels under the conditions of deformation with its unique [5], no experience of bolt support, there are not enough bolt support cases to provide engineering analogy in the country.
If engineering analogy method is not optional , this method will be possible

Optimization of reinforced concrete tall buildings using a hybrid genetic algorithm Haiyan Lu1, a Xiao Guo1, b 1 School of Architecture and Civil Engineering, Shenyang University of Technology, shenyang 110870, China (aSy-lhy@126.com, b tong_ke@126.com) Keywords: genetic algorithm; tall buildings; optimality criteria; hybrid method; strength; stiffness.
A design example is optimized to demonstrate the practicability and effectiveness of the proposed method Introduction For a reinforced concrete building whose topology and shape are fixed, the main task of the structural engineer is to determine the size of the member cross section and reinforcement detailing.
Although the structural engineer can obtain the structural responses subjected to multi-load cases by a number of available software packages, which, however, can not modify the member dimensions and reinforcement detailing automatically to satisfy specific regulations of the design codes.
