| 摘 要： | 预应力钢结构是一种将预应力与钢结构相结合，通过施加预应力充分利用钢材弹性范围内强度的新型结构。本文提出一种全新的预应力钢结构，此结构的突出特点是拼装式自平衡体系，即在充分利用轴心受压杆件长细比较小时使杆件发生强度破坏，达到充分发挥钢材潜力的目的。因此，在保证结构受压杆件和受拉钢绞线强度的前提条件下，根据建筑结构节点更强的原则及为了考虑施工方便、结构安全、结构耐久性等因素，对于构件设计、制作、加工及安装等问题的探讨是十分必要的。本文讨论一种新型结构及实验模型的构件加工、安装及在实际工程中的应用设想。

| Abstract: | pre-stressed steel structure is a kind of new structure that combines pre-stress and steel structure together. The strength in the elastic range can be utilized fully in the steel structure by imposing pre-stress. In the paper, a totally new prestressed steel structure is brought forward. The most obvious characteristic of this structure is the launching self-equilibrium system. We can utilize fully that the axial compression members easily occur strength breakage in small slenderness ratio, in order to exert the potent of steel materials. Under the precondition of ensuring tension of compressed bars and steel cables, it is quite necessary to study the problems such as members design, manufacture, process and installments according to the principle of constmction structure joint stronger and consideration about construction convenience, structure safety, structure durance and so on.The member process, installment and application of the new structure and its experiment model are discussed in the paper. |
