FREE SHEAR CONNECTION CALCULATOR
SkyCiv 剪切连接计算器
This shear connection calculator checks the plates, 角度, bolts and welds that carry a beam end reaction into its supporting member, 反对AISC 360-16 在 ASD 或 LRFD 中. It covers single and double plates, 单角和双角, end plates and directly welded webs.
Enter the configuration, the section sizes, the fastener arrangement and the design shear, and it returns a utilization ratio for every check with the code reference behind it. 它在浏览器中运行, 无需安装任何东西.
关于剪力连接计算器
The calculator sizes and checks a simple connection between steel members, the kind that delivers a beam end reaction into a column or a supporting beam. You choose the configuration, define the connecting element and the fasteners, then enter the design shear.
它报告每个限制状态的利用率，而不是单个通过或失败, 这样您就可以看到哪项检查接近于管理，如果不是则需要更改哪些内容.
什么是剪力连接?
A shear connection transfers vertical shear from one member to another, typically from a beam into a column. It is a simple connection: it is detailed to carry the end reaction and to rotate at the joint, not to carry end moment.
That rotation is the point. A moment connection has to be stiff enough to hold the beam end against rotation, which takes heavier plates, more welding and often column stiffeners. A shear connection is allowed to rotate, so it stays light and quick to fabricate, which is why it is the default choice wherever the frame gets its lateral stability from somewhere else.
剪切连接由哪些组件组成?
The components depend on the configuration, but they generally include:
- 板块: single or double plates bolted or welded to the beam and column.
- 角度: single or double angles connecting the beam web to the support.
- End plates: plates welded to the beam end, then bolted to the column.
- 螺栓: fasteners securing the plates or angles to the members.
- 焊缝: used in place of bolts, most often on the supported side.
- Direct welds: joining the beam web straight to the column face.
Most configurations are welded on one side and bolted on the other. The weld is made in the shop, where access and position are controlled, and the bolts are left for the field, where the erector needs something quick to make and a little tolerance to work with.
剪力连接常用在哪些地方?
Shear connections appear wherever a beam frames into a support and the frame gets its lateral resistance elsewhere, from bracing or a core. 常见的应用包括:
- 商业和住宅建筑框架.
- 钢框架工业设施.
- 桥梁和立交桥.
- 模块化结构和预制设计.
They are the most numerous connection in a typical steel frame, which is why small savings in plate size or bolt count repeat across a job.
存在哪些类型的剪切连接?
The calculator covers the configurations below, each suited to a different framing condition:
- 单板, also called a shear tab or fin plate: one plate welded to the support and bolted to the beam web. 通常是团体中最便宜的, with one weld line and one bolt group.
- Double plate: plates either side of the web, where one plate cannot carry the reaction.
- Single or double angle: angles bolted or welded to the web and the support. A double angle puts the web fasteners in double shear.
- 端板: a plate welded across the beam end, then bolted to the column.
- 直接焊接腹板: the beam web welded straight to the support, with no connecting element.
Picking between them is usually a fabrication question rather than a strength one. The reaction can be carried by any of them at the right size, so the choice comes down to access for the welder, what the erector can bolt up safely, and how much tolerance the fit-up needs.
如何使用剪力连接计算器
Work through the inputs in this order:
- 配置: pick single plate, 双板, single or double angle, 端板, or directly welded web.
- 会员: set the supported beam and the supporting column or beam, with their steel grades.
- Connecting element: the plate or angle thickness, width and depth.
- 灯具: 螺栓等级, 直径, 孔类型和布局, 或焊缝尺寸和电极强度.
- 设计荷载: the shear at the beam end, matched to the design method you selected.
然后运行设计检查. Match the load to the method: LRFD 根据设计强度考虑因子载荷, ASD 根据允许强度承受服务负载, 并且计算器无法识别您输入的内容.
If a check fails, the utilization ratio tells you which one and by how much. A plate limit state points at the plate thickness or depth; a bolt limit state points at the bolt count, diameter or edge distance.
为什么选择 SkyCiv 的剪切连接计算器?
每个公式, 完整显示设计检查和代码参考, 因此可以逐行读取工作，而不是从数字进行逆向工程. That matters when the calculation has to be checked by someone who did not run it.
它还在解决之前运行细节和冲突检查, which catch the connection that satisfies every strength calculation and still cannot be fabricated or erected. Bolts that cannot be reached with a wrench do not show up in a capacity equation.
