In oilfield, downhole derricks are the main part that bears the loads in the downhole operation hoist system.

在油田起下油井管柱的各种施工中，作业井架是主要的承力构件，井架的承载性能对井下各种施工作业产生直接影响。

Further more, the prestress loss , which is caused by the shortened beam member due to concrete shrink and creep, is of disbenefit to prestress concrete structure.

不仅如此，混凝土的收缩和徐变使构件缩短而引起预应力损失，对预应力混凝土结构十分不利。

The composite plate is divied into several regions, and every region contains a bolt hole.

由于钉孔的存在，这种连接方式容易引起应力集中，并导致构件破坏。

Following the establishment of the workability computation module of mechanism, this paper discusses how to quantify the workability of component parts and motion duals,and the calculating example is given, therefore the quantitative analysis of mechanism is made much more clear and definite.

继建立起机构工作能力的计算模型之后，讨论如何将构件和运动副的工作能力定量化，并给出了计算示例，从而使机构工作能力的定量分析更为明了。

Test results and model data indicate that appropriately designed and insulated FRP-strengthened beam-slab assemblies can achieve fire endurances of four hours or more.

试验结果和模型数据显示，正确设计和进行绝缘保护的FRP加强梁构件耐火极限能够达到4 h或者以上。

Therefore, we conducted a series of experimental research and engineering applications for the new steel-concrete composite structures.
