Modelling of the Restrained Beam Test
A full-scale eight-storey composite test building was constructed by BRE at its Cardington
Laboratory during 1994 to resemble a modern city-centre medium-rise office development
typical of current UK practice.Composite action was achieved between both primary and
secondary steel beams and the floor slabs using shear studs.The Restrained Beam Test was
carried out by British Steel plc (Bentley,1995a,1995b) on the frame in January 1995.It
involved heating a single secondary beam and an area of the surrounding slab on the seventh
floor.The member tested consisted of a 305x165UB40 section spanning between columns
D2 and E2,and was heated using a specially constructed gas-fired furnace along the middle
8m of its 9m length.The location of the test is shown in Figure 1.The extent of the structure
incorporated within the model is also indicated in Figure 1.
In the Cardington test building the total nominal thickness of the composite slabs was
130mm,with a 75mm continuous portion at the top,giving effective stiffness factors of 0.72
and 0.34 parallel and perpendicular to the rib direction.The ambient-temperature material
properties used in the modelling,based on test values where these were available,were as
follows:

为了模拟现代英国典型的市中心中等规模的办公室发展情况,1994年BRE在Cardington实验室构建了一座全尺寸的八层复合试验建筑,复合作用存在于主次钢梁之间,楼板采用shear studs.钳制梁测试于1995年1月由英国钢上市公司( Bentley,1995a 1995b)在该建筑上进行.这个试验是加热单个次梁和第七层上的围板的一部分.受试部分包括一个305x165UB40横跨在D2和E2之间的截面,用一个特殊构造的煤气加热炉沿着8m部分的中部加热.此次试验的位置如图1所示.图1中也显示了模型内部建筑物合并的程度.Cardington试验建筑中合成平板的标称厚度是130mm,顶端有一个75mm的延伸部分,其有效劲度因素为0.72和0.34,分别与横梁的方向平行和垂直.基于测定值,在此模型建筑物中用到的周围温度材料性质如下：
