The chords were formed from lengths

The chords were formed from lengths of steel spliced together using L shaped section of steel. The splices were connected using clinching. Fig. 12 shows the load–deflection behaviour of the truss throughout its full loading history During the test it was noticed that the splice in the bottom chord was beginning to open and this can be seen as the increase in rate of deflection.

从钢拼接在一起使用 L 形钢一节的长度形成了弦。接头连接了使用紧抓住的。图 12 显示在其整个完全加载历史桁架的 load–deflection 行为期间注意到在下弦拼接开始打开，这可以被视为偏转率增加的测试。

和弦是从钢材长度拼接在一起使用钢材L形截面形成的。的拼接都用铆连接。图。图12示出在测试过程中可以注意到，在下弦接头已开始打开，这可以被看作是增加的偏转速率在其整个满载历史桁架的载荷 - 挠度特性。

和弦是长度的钢形成拼接在一起，利用L形截面钢。接头进行连接使用连接。图12显示了负载偏转行为–桁架结构在整个加载历史测试中值得注意的是，在下弦拼接开始开放，这可以被视为在偏转速率增加。
