FREE BOLTED SPLICE CONNECTION CALCULATOR
SkyCiv Bolted Splice Connection Calculator
This bolted splice connection calculator returns the capacities and utility ratios for a splice between two I-shaped members joined by bolted flange and web plates. It works from the section dimensions, the plate depths, widths and thicknesses, the steel properties and the bolt layout you enter, and checks the joint to AISC 360-16.
A bolted splice is made on site during erection. Members arrive in lengths that can be transported and lifted, then carry moment, shear and axial load across the joint once the plates are bolted up.
关于螺栓接头连接计算器
The calculator covers splices between I-shaped members joined by bolted flange plates and a web plate. It returns the maximum moment capacity, the maximum shear capacity and the maximum axial capacity of the joint, each one as a capacity and a utility ratio, checked to AISC 360-16 在 ASD 或 LRFD 中.
The numbers come from what you enter: the depths, widths and thicknesses of the splice plates and flange plates, the steel properties of the section and the plates, the section dimensions, and the design loads at the splice.
什么是螺栓接头连接?
A bolted splice joins two structural members end to end so that force passes from one into the other. The members usually have an I-shaped cross-section, and the joint is made with a plate on each flange and a plate on the web, all bolted rather than welded.
Bolted splices are strong, they tolerate some fit-up variation, and they can be taken apart again. That combination is why they are a popular choice for flange and web splices made in the field.
该连接由哪些组件组成?
A bolted splice is built from four parts:
- 法兰板: a plate on the top flange and one on the bottom flange, carrying bending moment across the joint.
- Web plate: bolted to the web on each side of the joint to carry shear.
- 螺栓: the fasteners clamping every plate to the two members.
- The two members: the I-sections either side of the splice, whose dimensions and steel grade set what the joint has to match.
Together the plates and bolts connect the two members so they behave as one.
螺栓接头常用在哪些地方?
Bolted splices turn up wherever two members have to join and the connection has to be strong:
- Equipment support structures.
- Industrial frames.
- Pipe racks.
- Railway, automotive and mechanical structures.
- Mining and power transmission structures.
Bolted splices are not limited to those. The detail suits anywhere two members have to join and act as a single member.
What Alternatives Exist to a Bolted Splice?
The alternative is a welded splice. The choice comes down to where the work happens: bolted splicing is normally used when members are joined during erection, and a joint made in the shop instead can be welded.
So the question to settle early is whether the splice is a field joint or a shop joint. That decides the detail before any of the plate sizing starts.
How to Use the Bolted Splice Connection Calculator
Enter the geometry, the materials and the design actions at the splice. 输入是:
- Section steel: yield and ultimate strength.
- Section geometry: the dimensions of the I-section.
- Splice plate steel: yield and ultimate strength.
- 法兰盘: 深度, width and thickness.
- Web plate: 深度, width and thickness.
- 螺栓: the bolts used and the bolt configuration.
- 设计荷载: 片刻, shear and axial.
Click run and the calculator works through the checks. Results come back as both utility ratios and capacities, and the report carries the detailed calculations behind them.
Why Choose SkyCiv for Bolted Splice Design?
Every check is reported as a capacity alongside a utility ratio, so an overloaded plate or bolt group shows up without reading the whole report. The calculations are set out in full rather than returned as a single verdict, and the tool runs in the browser with nothing to install.
The full SkyCiv Connection Design module picks up where the free tool stops: 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.
