FREE STEEL CONNECTION DESIGN CALCULATOR

無料の鉄骨接続設計電卓

This free steel connection design calculator models and checks a steel connection in your browser, AISCへ 360-16 in ASD or LRFD and to AS 4100:2020. 接続を選択してください, set your members, 治具と負荷, そして解決します.

It is the same software as the paid module and carries the same connection library, so every joint type is available: 剪断, せん断プラス軸方向, 瞬間, 柱と梁の接合, そしてブレース接続. There is nothing to install.

About the Free Steel Connection Design Calculator

The calculator runs the full SkyCiv Connection Design engine. You choose a configuration from the template library, define the members and the connecting elements, set the bolts or welds, and enter the design actions.

It reports a utilization ratio against each limit state rather than a single pass or fail, so you can see which check is close to governing and what to change if it is not. 設計エンジニア, 請負業者や製造業者が使用します, コースワークに取り組んでいる学生も同様です.

American and Australian Standards for Connection Design

電卓は次のように設計されています AISC 360-16 ASD または LRFD の場合, そしてへ なので 4100:2020. AISC 作業はインペリアル単位またはメートル単位で実行できます, とAS 4100 メトリックで実行.

Pick the design method before you enter loads. LRFD takes factored loads against design strength and ASD takes service loads against allowable strength, and the calculator cannot tell which you typed.

Connection Types You Can Design

The library holds over 80 事前設定された接続タイプ. Most are available framing to a column flange, a column web or another beam’s web, which is where the count comes from. They are grouped by the members being joined.

I-Shape to I-Shape Connections (AISC)

The largest group, covering beam to column and beam to beam framing:

HSS to I-Shape Connections (AISC)

For a beam framing into a hollow structural section column:

  • 剪断: 単一角度, ダブルアングル, 単板, single WT and seat angle.
  • せん断プラス軸方向: 単板.
  • 瞬間: フランジプレート.

Channel to Channel Connections (AISC)

Channel sections are covered for shear, using a directly welded web or a single plate.

Bracing Connections (AISC)

The bracing group covers the gusseted joints in a braced frame:

  • Vertical brace: 単板, ダブルアングル, end plate or directly welded to the column, each with a lower brace only, an upper brace only, または両方.
  • Chevron brace: directly welded gusset plate.
  • 膝のブレース: directly welded gusset plate.
  • Truss brace: the knee and chevron gusset configurations, applied to a truss node.
  • Horizontal brace: single plate or single angle to the support, with or without a column at the joint.

ブレースは AISC でのみ利用可能です.

なので 4100 接続

なので 4100:2020 covers shear connections between I-sections: the web side plate, フレキシブルエンドプレート, シングルアングルとダブルアングル.

セクション, Grades and Fixtures

ワイドフランジ, HSS, WT, L および 2L プロファイルは AISC で利用可能です, AS のユニバーサル梁とユニバーサル柱 4100. 部材の標準鋼種, プレートとファスナーは事前にロードされています, and you can enter your own Fy and Fu where a grade is not listed.

Every interface can be ボルト締め または 溶接された. For the fastener side on its own, ある bolt calculator と weld calculator.

How to Use the Free Steel Connection Design Calculator

Work through the tabs in this order:

  1. Code and category: pick AISC 360-16 またはAS 4100:2020, the units, and the members being joined.
  2. 構成: choose the connection type from the template cards.
  3. 組み立て: set the supported and supporting members, their sections and grades.
  4. 繋がり: the plate or angle geometry.
  5. 備品: ボルトグレード, 直径, 穴の種類とレイアウト, or weld size and electrode strength.
  6. 負荷: the design actions, matched to the method you picked.

Then run the design checks. Anything missing from an earlier tab is flagged rather than silently defaulted, and the detailing limitation table flags a connection that satisfies every strength calculation but still cannot be fabricated or erected.

What the Free Version Limits

The free calculator is the same software and carries the same connection library. What it limits is how much you can change and how much of the results you see.

  • Solves: a free user gets 20 design check runs per week.
  • 結果: the demand is shown for every check, but the capacity and the ratio are locked on the back half of the design checks and the detailing limits. An odd count rounds the shown half down, so a section holding a single check is locked outright.
  • 報告する: the detailed calculation report is not produced.
  • Files: connection files cannot be saved or loaded.
  • 入力: bolt hole type, 断面形状, メンバー, ボルトと溶接の材料, ボルト径, 接続要素と溶接面はデフォルトのままで、PRO とマークされます。.

あ 無料アカウント is what lets you save and reload your work.

Why Choose SkyCiv Connection Design

完全な SkyCiv接続設計 module unlocks all of the above. Its report writes out every calculation step with the equation, AISC での設計テーブルとその条項の由来 360-16 またはAS 4100:2020, so the working can be read line by line instead of reverse-engineered from a number.

It also runs the detailing and clash checks before the solve, produces CloudCAD detail drawings alongside the calculation report, and exports 3D connection geometry directly to IFC. It runs entirely in the cloud, ダウンロードなし, アップデートまたは IT セットアップ.

It checks the connecting elements and their fasteners against the actions you enter. That covers bolt shear, ボルトの張力, combined tension and shear interaction, 溶接スロート応力, plate yielding, plate rupture, ブロックせん断破壊, プレート曲げ, and the local limit states of the supporting member.

Each one is reported as a utilization ratio with the code reference behind it.

以上 80 pre-configured types. 剪断, shear plus axial and moment connections between I-shapes, HSS to I-shape connections, channel to channel shear connections, 柱と梁の接合, and the vertical, シェブロン, 膝, truss and horizontal bracing connections.

両方. Each interface is set independently, so the common arrangement of a shop weld to the support and a field bolt to the supported member is modelled directly. Several configurations, such as the directly welded web, remove the connecting element altogether.

はい. A connection that delivers concentrated forces into a column raises local limit states in that column, and web local yielding, ウェブの麻痺, web shear and local flange bending are checked alongside the connecting elements.

This is what usually decides whether transverse stiffeners are needed, and it is the check most often missed when a connection is sized by hand.

It is the demand divided by the available strength for that limit state, so anything at or below 1.0 passes. The governing check is the highest ratio, and that is the one to change if the connection needs more capacity.

A ratio well under 1.0 across every check usually means the connection is heavier than it needs to be.

A free user gets 20 design check runs per week. The demand is shown for every check, but the capacity and ratio are locked on the back half of the design checks and detailing limits, the detailed calculation report is not produced, and connection files cannot be saved or loaded.
