However, for rate-dependent materials and devices, such as viscous dampers or the recently developed triple friction pendulum isolators, RTHS is essential.
All facing materials are bearing on the top and bottom lumber pieces.

Experimental Study on Specimens of Steel Secondary Beam Embedded in Reinforced Concrete Girder of Frame Structure Qiong Yua, Zhoudao Lub, Jiangtao Yuc, Xingzhuang Zhaodand Jin Daie Institute of Structural Engineering and Disaster Reduction, Tongji University, Shanghai 200092, China ayiongyu2005@163.com, blzd@tongji.edu.cn, cyujiangtao@tongji.edu.cn, dzxz_342@163.com, edaijin_2008@qq.com Key words: Superposition of shear and torsion, Rotational angle, Embedded coefficient, Pullout failure, Joint failure.
But in engineering practice, the linear rigidity of the frame girder is smaller, so a weaker restraint action of concrete girder on steel beam, a bigger deflection of the steel beam, a larger moment in the mid span steel beam, and a lower load capacity of the steel beam are resulted.
In the definition of contact property, in relation to normal action the hard contact is selected for contact pressure and the gab in between, and for tangential action the coulomb friction model is chosen. 5.2 Material properties The concrete damaged plasticity model and the stress-strain diagrams for uniaxial tension and compression recommended in Code for design of concrete structures (GB50010-2002) of china are applied [9].

Safety analysis of tunnel in gob of high steep thick coal seam (Ⅰ) ——2-D numerical simulation for response of surrounding rock to extraction Wenbin Lu1,2,a, Yimin Wu1,b, Jie Chen3,c, Helin Fu1,d 1School of Civil and Architectural Engineering, Central South University, Changsha 410075,China; 2Hunan Urban Construction College, Changsha 411101,China; 3Tongling Transport Bureau, Tongling 244000, China a luwenbin_csu@163.com,b wuyimin531@163.com,c cjgck0425@163.com,d fuhelin100@sohu.com Keywords: Tunnel in gob of coal seam, high steep coal seam, surrounding rock, impact of mining, numerical simulation.
According to statistics, steep seam coal mine can be accounted about one-sixth of the key national mine, and coal mines with steep seam coal account for almost 40% in the south[1,2].
Figure 2 Schematic diagram of Wusongshan Tunnel through the coal mine (left: plan; right: profile) 2 Numerical simulation plan 2.1 Numerical Model ① numerical simulation software: ANSYS. ② the model range: the left lane of the tunnel axis to make vertical section as analog plane, height from the surface to-400m, height of about 500m; length to self K1 +100 K1 +600, about 500m. ③ element type: SOLID42. ④ material constitutive: D-P model. 2.2 Simulation cases The basis situation of coal seam is listed as following: the range from the surface to -30m level is the early small coal mine, and the mining is unknown; the range of -30m ~-300m level is the Wusong Coal Mines, and the mining plan basically clear.

If this principle is good in all cases, then there is no need to take into consideration the center of symmetry of the set S, since for example if one has a 2D factory piece which has heterogeneous material density, then its center of weight (barycenter) is different from the center of symmetry.

In the late 60s of the last century, when the term mechatronics was coined, it included just mechanical and electrical engineering.
With growing system complexity, computer engineering was unavoidable and welcomed.
Irrespectively of the formal methodology [3], [4], [52], the engineering design process leads to a mathematical optimization problem.
As already mentioned, mechatronic engineering problems are usually continuous or discrete in their parameter space.
