| 摘 要： | 为了简化计算,提高计算精度,解决将箱梁比拟成正交同性板时,其横向抗弯刚度Dy、综合抗扭刚度日与实际值出入较大的难题,该文采用正交异性板在桥跨结构静力分析上的独特优点,选择箱梁桥跨结构比拟法的难点Dy的确定作为突破口,通过空腹框架比拟导出了等效Dy的普遍公式;再代人通过构造异性板理论导出的,以Dx、Dy函数关系表示的H公...

| Abstract: | In order to simplify the calculation, enhance the calculating precision and solve the problem that its lateral bending rigidity Dy, and integrated torsional rigidity H are greatly different from the practical value when the box beam is assimilated as the isotropy plate, the article uses the specific advantage of orthotropic plate in the static analysis of span structure, selects the determination of difficulty Dy of box beam span structure assimilation method as the gap, assimilates and educes the universal... |
