中文摘要: |
本文以西部某城市斜交箱梁桥为工程背景,利用有限元分析软件Midas Civil建立了不同斜交角度的有限元分析模型,运用时程分析的方法,研究了在跨度相同的条件下,斜交角度对斜交梁桥动力特性和地震反应的影响。经过分析,所得结果表明:斜交角度是影响其动力特性的一个重要参数,且对斜交桥的抗扭刚度和地震反应有较大的影响。 |
英文摘要: |
This paper takes a skew box-girder bridge in a western city as the engineering background ,the finite element analysis model is established for the different skew angle by using the finite element analysis software called Midas Civil. Using the method of time history analysis, studied in the span,pier height under the same conditions, skew angle has an influence on the dynamic characteristic and seismic response of skew girder bridge. Through analysis, the results show that: the skew angle is one of the most important factors that affect the dynamic characteristics, and has a great influence on the skew bridge’s torsional stiffness and seismic response. |
