一、前言用有限条法分析连续弯箱梁空间结构,所需内存容量小、计算时间短、费用低,并可用中型计算机进行计算.其结果又能满足设计需要和使用要求.我们对所编程序,用一般简单示例进行分析验证之后,又结合×××市双层立交桥进行了三孔连续弯箱梁桥的详细分析,取得了满意结果.使我们对连续弯箱梁这一空间结构的性能加深了理解,并对所编程序进行 I. Preface Using finite strip method to analyze the spatial structure of continuous curved box girders, the required memory capacity is small, the calculation time is short, the cost is low, and the calculation can be made by a medium-sized computer, and the results can meet the design requirements and the usage requirements. Program, with a simple example for analysis and verification, combined with ××× City double-decker bridge for a detailed analysis of three-hole continuous curved box girder bridge, and achieved satisfactory results.We make continuous curved box beam spatial structure Performance deepens understanding, and the programmed procedures
