A component method has been introduced by Steel Construction Institute to predict the moment resistance of partial strength connection. The design philosophy is taken directly from Eurocode 3 with strength checks on bolts, welds, and steel which have been modified to comply with BS 5950-1:2000. The accuracy of the method however needs to be validated with the experimental tests especially for hot-rolled sections other than typical British Section (BS). Six experimental tests on beam-to-column connections have been carried out for Flush End-Plate (FEP) connections consisting of variable parameters such as thickness of end-plate, size and number of bolts, size of columns, and beams. The tests were set-up using local hot-rolled steel sections known as Perwaja Section (PS) for beams and columns instead of typical British Section (BS). The strength of materials for end-plate, column and beam sections were tested for tensile strength and used in predicting the moment resistance for component method. The moment versus rotation of the test results were plotted and compared with the moment resistance derived from component method. The study concluded that the moment resistance of the tested flush end-plate connections was higher than the predicted moment resistance from component method which showed good agreement between the two moments. The study also concluded that the tested FEP connections met the requirements and criteria of partial strength connections.

使用热轧珀瓦哈钢型材的齐平端板连接的零件方法与实验测试的比较

钢结构研究所已经引入了一种分量法来预测部分强度连接的抗弯矩。设计原理直接取自Eurocode 3，对螺栓，焊缝和钢进行了强度检查，并对其进行了修改，以符合BS 5950-1：2000。但是，该方法的准确性需要通过实验测试来验证，尤其是对于除典型的英国型钢（BS）以外的热轧型钢。对于平端板（FEP）连接，已经进行了六项梁到柱连接的实验测试，其中包括可变参数，例如端板的厚度，螺栓的尺寸和数量，柱的尺寸和梁。使用局部热轧钢型材（称为梁和柱的Perwaja型材（PS））代替典型的英国型材（BS）进行测试。测试了用于端板，柱和梁截面的材料强度的拉伸强度，并将其用于预测组件方法的抗弯矩。将测试结果的力矩与旋转作图，并将其与从分量法得出的力矩阻力进行比较。研究得出的结论是，经过测试的齐平端板连接的抗力矩性能高于组件法预测的抗力矩性能，这表明两个力矩之间具有良好的一致性。研究还得出结论，测试的FEP连接符合部分强度连接的要求和标准。绘制了测试结果的力矩与旋转的关系曲线，并将其与由分量法得出的力矩阻力进行了比较。研究得出的结论是，经过测试的齐平端板连接的抗力矩性能高于组件法预测的抗力矩性能，这表明两个力矩之间具有良好的一致性。研究还得出结论，测试的FEP连接符合部分强度连接的要求和标准。绘制了测试结果的力矩与旋转的关系曲线，并将其与由分量法得出的力矩阻力进行了比较。研究得出的结论是，经过测试的齐平端板连接的抗弯阻力高于根据分量法预测的抗弯阻力，这表明两个弯矩之间具有良好的一致性。研究还得出结论，测试的FEP连接符合部分强度连接的要求和标准。
