The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.

网壳通过可径向滑动球铰支座与下部混凝土结构连接，网壳周边设置封闭环形约束桁架，中间单层壳体部分利用建筑凸肋造型设置加劲桁架，解决了保证整体稳定和减小温度应力之间的矛盾，同时避免了网壳侧推力直接传递给下部混凝土结构，简化了网壳支座及下部混凝土结构的设计，节约了混凝土结构的造价。

Aiming at calculation of the equivalent rigidity of truss stiffening girder in an aeroelastic model design of a long-span suspension bridge with truss stiffening girder,Aizhai bridge,a super-long -span suspension bridge across deep valley with single span,was taken as an example for investigation.

针对大跨度桁架加劲梁悬索桥气弹模型设计中主梁等效刚度计算问题，以矮寨大桥为实例，建立不同长度空间桁架加劲梁节段模型有限元模型，通过悬臂梁位移法反算得到主梁的等效刚度特性，研究了不同荷载施加方式以及不同梁段长度对等效刚度特性的影响。

This text absorbs advantages of the above two types of bogies. It is adopted the structural type of H type truss with bogie elastic articulation. Its characteristics are: the truss is welded together by two U type side beam and two steel pipes.

本文吸收了上述两种转向架的优点，采用了H型构架与摇枕弹性联结的结构型式，解决了上诉两种转向架存在的问题。

In responding to the problems identified, a countermeasure of bolt-mesh-anchor-shotcrete + floor-bolt + truss coupling supporting is proposed, namely using shotcrete to seal surrounding rock, bolt-mesh support to release deformation energy, floor bolt to transfer floor heave plastic slippage force, anchor-truss support to control the deformation of surrounding rock. Therefore, the effective deformation control of deep high stressed soft rock roadway can be achieved.

为此，提出了锚网喷＋锚索＋底角锚杆＋桁架耦合支护对策，即通过喷层封闭围岩，锚网柔性支护释放变形能，底角锚杆转移底臌塑性滑移作用力，锚索＋桁架支护控制围岩整体变形，从而实现对高应力巷道围岩变形的有效控制。

Steel Truss.It is the load-bearing part in the roof structure. It can be triangle, trapezoid, shuttle and three-hinged. Angle bar steel, thin steel sheet, round bar and square bar can be used to manufacture it.

桁架：桁架是屋盖结构中主要承重构件，桁架的形式有三角形，梯形，梭形，三铰捞等，可采用角钢薄壁型钢，园管，方管等来制作。

When Horizontal braces were set in the roof-truss, that could make more capacity effectively, and angle brace too.

另外，屋架中在加设平角撑或斜角撑时，皆能有效的帮助屋架来抵抗各种载重能力。

The assembly of complex joints, welding sequence, precision control technology and truss arching are also presented.

并对复杂节点组装顺序、焊接顺序、精度控制技术和桁架起拱进行了研究。

Considering the axial symmetry of the structure, the computation model can be simplified as a planar truss.

考虑到该结构是一种轴对称结构，将结构简化为半榀平面桁架，采用节点平衡理论进行分析。

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。
