便橋吊裝作業高度依賴技術工的經驗與技巧，且存在高空作業風險，因此，本研究基於快速組裝便橋的梁構件自動化接合施工上，提出一個適用於梁對梁的鋼結構自動組裝接頭設計與使用吊車之吊裝施工法，其中包含定義接頭設計目標與概念、幾何參數設計方法與吊裝施工法；最後利用有限元素法分析不同受力下接頭結構行為，並利用縮尺模型驗證工作性，結果顯示，在梁與梁自動組裝目標下，本研究提供一個基於施工導向出發的新型結構接合元件設計方法，借助重力觸發旋轉接合並利用吊車吊裝的方式，達成自動化組裝施工。

Erections highly relies on technicians' experience and expertise for construction of a temporary bridge. Meanwhile, these technicians need work at height over a certain amount of time and may suffer in a highly risky work environment. In this study, a beam-to-beam structural connector design is proposed for a temporary bridge with an automated assembly solution. This design procedure accompanies a mobile crane and aims at (1) unmanned operations at height, (2) the connector with a capability of supporting the weight of the beam; (3) simple assembly mechanism, (4) observable assembly process, and (5) massive production of the connector. Moreover, a workable prototype connector is also developed, and the mechanical behavior is studied and evaluated by the finite element method. As a result, this study provides an innovative construction-oriented design method for beam-to-beam connections of a temporary bridge as well as can contribute to the automation in construction.
