钢结构技术的整体设计已经驾轻就熟，但在连接方面往往呈现的方式单调或概念模糊，但事实上，钢构件的联合设计也受很多条件。

 

1.连接手段的限制

 

钢结构的施工特点之一是工厂加工和现场组装。这与传统的砌体方法不同，后者产生大量的接缝。连接各种型材的方法主要有三种：铆接、焊接和螺栓连接。铆接是钢结构建筑早期常用的铆接方法。施工简单，但需要在构件上挖洞以降低截面性能，接头处容易产生集中应力，比较近很少使用。焊接接头外形简洁，连续传力效率高，但施工要求高。后期出现的高强度螺栓连接也能满足现代钢结构中广泛应用的类似焊接的强度要求。

2.构件的来源

 

理论上钢构件或具有任意加工的连接构件，但在每一个特定的项目，结构构件与连接构件总是被实际条件的限制。有经验的设计师通常会选择现成的，易于安装的钢板，并设计有连接部件的简单而有效的连接。

3.连接构件是分层的。

复杂的逻辑层次结构中，存在复杂且具有逻辑的层级关系，这种差异反映在分级关系和所述安装构件具有钢的建筑结构系统之间的尺寸。连接对象是实现层级转换，而且还从三维实现力变换到二维，比较终向构件的临界尺寸。由大致复杂的三维连接构件，连接构件的平面完整组合物相连接。

 

4.连接部件平面

 

两个线性结构构件总是在同一个平面上，即构件应力的平面，为了有效地抵抗该平面内的应力、弯矩或剪切力，通常在该平面内设计连接构件，如钢管与电缆之间的焊接板总处在两者形成的平面内。在多个构件连接的情况下，组合的平面构件可以对应于立体的受力情况。

The overall design of steel structure technology has been mastered easily, but the way of connection is often monotonous or fuzzy, but in fact, the joint design of steel members is also subject to many conditions.

 

1. Restrictions on connection means

 

One of the construction characteristics of steel structure is factory processing and field assembly. This is different from the traditional masonry method, which produces a large number of joints. There are three methods to connect various profiles: riveting, welding and bolting. Riveting is a common method in the early stage of steel structure construction. The construction is simple, but it needs to dig holes in the components to reduce the section performance. The joint is easy to generate concentrated stress, which is rarely used recently. The shape of welding joint is simple, the continuous force transfer efficiency is high, but the construction requirements are high. The later high strength bolt connection can also meet the strength requirements of similar welding widely used in modern steel structures.

 

2. Source of components

 

In theory, steel members or connecting members with arbitrary processing, but in every specific project, structural members and connecting members are always limited by actual conditions. Experienced designers usually choose ready-made, easy to install steel plates and design simple and effective connections with connected parts.

 

3. The connecting members are layered.

 

In a complex logical hierarchy, there is a complex and logical hierarchical relationship. This difference is reflected in the size between the hierarchical relationship and the building structural system in which the installation component has steel. The connection object is to realize the level conversion, and also from three-dimensional to two-dimensional, and finally to the critical size of the component. It is connected by a plane complete composition of a substantially complex three-dimensional connecting member.

 

4. Connecting part plane

 

Two linear structural members are always in the same plane, that is, the plane of member stress. In order to effectively resist the stress, bending moment or shear force in the plane, the connecting members are usually designed in the plane. For example, the welding plate between the steel pipe and the cable is always in the plane formed by the two. In the case of multi-component connection, the combined plane component can correspond to the three-dimensional stress situation.
