中文摘要：

针对中国《钢结构设计规范》中对螺栓最小容许距离的规定与德国规范不同,选择普通螺栓连接的连接板作为研究对象,对比两国规范规定的效果差异;选择多种栓距进行拉伸对比分析,利用大型通用软件ANSYS对两国规范容许的最小距离即3倍和3.5倍螺栓孔径栓距的试件进行对比,分析两者的应力分布规律,并对两国容许栓距范围内的栓距进行研究。结果表明：栓距增大,试件的弹性极限和屈服极限承载力有所提高,在德国规范下试件承载力有所提高,结构更加稳定。

英文摘要：

According to the difference of minimum allowable bolt distance in Code for Design of Steel Structures of China and German specification, the connecting plate which was connected with common bolts was selected as object, and the effect differences of the two specifications were compared. Tension comparative analysis was carried out with various bolt distances. The minimum allowable distances of the two specifications which was 3 times and 3. 5 times of the diameter of bolt hole were compared using the large general software ANSYS, and the stress distribution law was analyzed. The allowable bolt distances of the two specifications were studied. The results show that the elastic limit and yield limit of specimen increase with the increase of bolt distance. Under German specification, the bearing capacity of component is improved and the structure is more stable.
