摘　　要：钢结构节点连接是钢结构工程中的一个重点。许多钢结构事故及震害都表明钢结构大多是由于节点首先破坏而导致结构的整体破坏。螺栓连接是钢结构的连接方法之一,分为普通螺栓连接和高强螺检连接,有些连接是在复杂外力作用下工作。为了保证螺栓连接件工作安全可靠,必须对其强度进行深入分析。假设研究的材料性能为线弹性,多个力作用效应符合叠加原理,利用材料力学基本原理,可以解决普通螺栓连接在多个外力作用下的强度计算问题。The complete construction system can be perfect only if all kinds of frame members in steel structure construction connect the factory together with building site.The connection between steel structures,that is to say,the connection between structure nodes is the key in steel structure project.Many steel structure accidents and accidents caused by earthquake show the damage to total steel structure firstly results in the damage to nodes.Bolt fastening is one of the main fastening ways in modern steel structure,which can be divided into common bolt fastening and high-strength fastening,in them,some fastenings are used in complex carrying ability.So the strength analysis must be done for insuring the fastenings in good condition.The actual practice shows the broken area of bolts group must lie in the maximal deforming section.Supposing the material for researching is flexible,the effect of multi-forces need correspond to the superposition principle in Material Mechanics.Therefore,the problem of strength calculation of common bolts in exogenic action can be solved well according to steel structure national norm and basic theory in Material Mechanics.
