FREE COLUMN SPLICE CONNECTION CALCULATOR
SkyCiv 柱接头连接计算器
This column splice connection calculator checks the bolted flange plates and web plates joining two W-shaped columns, and returns the capacity and utility ratio for strong-axis moment, 紧张, 压缩和强轴剪切. 检查遵循 AISC 360-16, 在 ASD 或 LRFD 中.
Columns in multi-story frames are spliced because a single length cannot be fabricated, transported and handled in one piece. The splice has to pass load and moment from the column above into the column below as though the member were continuous.
关于柱拼接连接计算器
The calculator works on splices between W-shaped columns joined by bolted flange plates and web plates. 它评估强轴力矩, 紧张, compression and strong-axis shear from the properties of the columns and plates you enter, reporting each as a capacity and a utility ratio.
检查遵循 AISC 360-16 在 ASD 或 LRFD 中, and the output includes the calculations behind the numbers rather than a bare pass or fail.
什么是柱拼接连接?
A column splice joins two vertical members, usually W-shaped columns, 延长它们的长度. Flange plates and web plates are bolted across the joint so the two segments behave as one member.
Splices are what let columns in high-rise construction be fabricated and transported in lengths that can actually be handled. The connection carries axial force, moment and shear, so the frame above is supported as though the column ran uninterrupted.
What Components Make Up a Column Splice?
Four parts make up the connection:
- W-shaped columns: the vertical members supporting the structure.
- 法兰板: bolted to the column flanges to transfer bending moment.
- 网版: bolted to the column webs to resist shear.
- 螺栓: the fasteners holding the flange and web plates in place.
Together they move load and moment across the splice and keep the two column segments continuous.
Where are Column Splices Commonly Used?
Column splices appear wherever a column runs taller than one fabricated length:
- High-rise buildings needing column extensions.
- 具有多层框架的工业结构.
- Bridge piers and other infrastructure.
- 塔楼和高层机械结构.
The calculator suits all of these, because the checks depend on the columns, plates and loads you enter rather than the structure around them.
What Are the Benefits of a Column Splice?
- 运输和装卸: columns can be fabricated in shorter sections that are easier to move and lift.
- Structural continuity: load transfers between segments, so the spliced column acts as one member.
- 行动范围: 相同的细节可以暂时设计, 紧张, 压缩和剪切.
- 代码检查: 产能遵循 AISC 360-16, 在 ASD 或 LRFD 中.
如何使用柱接头连接计算器
Enter the columns, the plates, the bolts and the design actions at the splice. 输入是:
- W-shaped column properties: dimensions and material properties of the connected columns.

Why Choose SkyCiv for Column Splice Design?
Each check is reported as a capacity next to a utility ratio, so an overloaded plate or bolt group is obvious without reading the whole report, and the workings are shown rather than hidden. 它在浏览器中运行, so a splice can be sized without installing anything.
The full SkyCiv Connection Design module extends that: 超过 80+ 预配置的连接类型, detailing and clash checks run before the solve, CloudCAD 详细图纸, 并将 3D 连接几何形状直接导出到 IFC.
