在美国钢结构学会（American Institute of Steel Construction）的赞助下，已经开发出了测试设备，可以将各种期望的轴向荷载和端弯矩组合应用于金属柱。8英尺、12英尺和16英尺的长度可容纳在该装置中，该装置设计用于测试最大为8WF40轧制截面尺寸的钢柱。 轴向载荷由一台容量为800000磅的万能试验机施加。端部力矩通过杠杆臂单独施加，杠杆臂上有张力-压缩液压千斤顶，千斤顶与测力仪串联安装，测力仪测量推力。 测试柱在荷载下的行为通过使用四种测量技术确定: 1.拉紧钢丝和镜子挠度计，2。水平杆，3。SR-4应变计和4。粉饰。 此外，产生力矩的推力由铝管测功机测量。 该测试项目目前由焊接研究委员会赞助。给出了一些测试结果，以证明该装置的有效性。描述了该程序的目标，主要目标是确定钢柱在不同端弯矩和直接荷载组合下的极限强度。

Under sponsorship of the American Institute of Steel Construction, test equipment has been developed in which various desired combinations of axial load and end moments may be applied to metal columns. Lengths of 8, 12, and 16 feet may be accommodated in the apparatus, which is designed to test steel columns up to an 8WF40 rolled section size. Axial load is applied by a universal testing machine of 800,000 pound capacity. The end moments are applied separately through lever arms with tension-compression hydraulic jacks mounted in series with dynamometers which measure the thrust. The behavior of test columns under load is determined by the use of four measuring techniques: 1. taut-wire and mirror deflection gages,2. level bars,3. SR-4 strain gages, and4. whitewash. In addition, the moment producing thrust is measured by aluminum tube dynamometers. The test program is currently being sponsored by the Welding Research Council. Some of the test results obtained are presented to demonstrate the effectiveness of the apparatus. The Objectives of the program are described, the principal one being to determine the ultimate strength of steel columns under varying combinations of end moments and direct load.
