摘要
有限元法和有限条法都可用于箱梁的空间分析。但是 ,有限元法计算量庞大。有限条法对于简支无内横隔的箱梁来说是很有效的 ,但对于多跨连续箱梁以及有内横隔箱梁的处理是不理想的。本文作者提出的差条法为箱梁的空间分折提供了一种较为理想的方法。
The space analysis of the box girder can be effected by both the finite element method and finite strip method. But the former needs a great amount of calculation, and the latter, though effective in case of the simple supported box girder without internal diaphragms, is not satisfactory incase of multiple-span continuous box girders with the internal diaphragms. The difference strip method, which is more desirable, is provided here.
