Domestic unseating prevention system without design is done as construction measures, which, therefore, can't ascertain the effect of unseating prevention system.

目前国内所采用的防落梁装置一般是作为构造措施，没有经过计算和设计，在地震作用下很难起到真正的防落梁效果。

The shaker mount is first moved a small distance toward the arch ends to ensure that the arch possesses two stable equilibrium positions, one on each side of the base line. The spring connecting the arch end and the mechanical shaker is carefully chosen such that small shaker stroke can induce large vibration amplitude of the arch.

此外，我们在激振器与拱形梁之间外加一个弹簧做连接，这可使激振器在仅能达到有限的激振振幅下，仍能使拱形梁端点有足够大的振幅产生，并使之能够发生折断式挫曲现象。

In addition, the results show that the temperature effect has significant influences on the deformations and stress of the box beam, therefore the temperature effect should be considered seriously during constructing and designing concrete box-grid bridges.

结果表明：在结构荷载不变的情况下，箱梁的温度应力较易测得；温度对箱梁的应力和挠度均有较大影响，在设计中应予以重视。

Finally this paper represents the comprehensive case study and analysis of temperature effect of the concrete box girder.

同时结合具体的工程实例，对混凝土箱梁的温度效应进行较为全面的研究，系统地分析了混凝土箱梁在日照辐射作用下的温度场分布规律、温度应力及日照温差效应产生的悬臂端位移，并将计算结果与未考虑温度荷载情况进行了对比与分析。

梁上好后，在梁上的木瓦工将事先准备好的一篮一篮的糕馒往下抛，下面的人就哄抢，抢到的以为荣耀，抢不到的到抢到的人手中去夺。

The cold-formed sheet is a groove-shaped structure that is composed of a crown plate and reinforced ribs connected with ends of the crown plate; the box beam is a box-shaped structure comprising an upper wing edge, a lower wing edge and two side webs that are connected in every two components.

由压型钢板、纤维增强塑料箱梁组成，压型钢板为由顶板和顶板端部的加强肋相连组成的槽形结构，箱梁为由上翼缘、下翼缘和两侧腹板两两相连组成的箱形结构，其结构如图所示。

Moreover,according to this method,the deflection curve equation of other kinds of variable section beam will be also carried out.

本文利用积分法求出了变截面悬臂梁在各种不同载荷作用下的挠曲线方程，而对于其它类型的变截面梁，都可以按照这种方法去求解。

With a 586 computer and ALGOR FEAS software of finite element method, the static stresses of the equalizing bar are obtained by finite element analysis for three finite element models of beam, plate and brick element.
