摘要
焊接工字形楔形梁常用于建筑结构中 ,我国现行钢结构设计规范 (GBJ1 7- 88)对它的计算却无相应内容 .本文用有限元方法计算了楔形梁的极限承载力 ,通过用等截面梁的稳定系数来代替楔形梁的稳定系数 ,进而推导出了楔形梁的稳定设计公式 ,该公式避开了楔形梁的众多参数 ,在应用上是简便安全可行的 .
Welding I-section tapered beam is often applied in structure engineering.In our country the present steel structure code(GB J17-88)has not relevant content of it.In this paper the ultimate strength of tapered beam is calculated by finite element method.The design formula of stability for tapered beam is developed by the method of uniform beam,which made the design simptified and secure.
