本文收集了 58 次主要承受剪力载荷的铝板梁试验的结果，形成了一个实验数据库。然后将结果用于评估铝梁的各种设计方法。结果表明，最初为钢板梁开发的张力场方法可以预测铝梁的不安全倒塌荷载。埃文斯和伯特提出的对该方法的修改被证明可以产生始终安全但相当保守的结果。新的极限状态设计规范 BS 8118 还将为腹板和任何横向或纵向加劲肋提供安全设计。尽管新代码非常保守，但与之前可用的代码 CP 118 相比，它表现出了非常显着的进步。
This paper gathers together the results of 58 tests on aluminium plate girders, loaded predominantly in shear, to form an experimental database. The results are then used to appraise various design methods for aluminium girders. It is shown that the tension field method, as originally developed for steel plate girders, may predict unsafe collapse loads for aluminium girders. A modification of the method, proposed by Evans and Burt, is shown to produce results that are always safe although rather conservative. The new limit state design code BS 8118 will also produce safe designs for the web panels and any transverse or longitudinal stiffeners. Although tne new code is very conservative, it is shown to represent a very significant advance from the previously available Code CP 118.
