摘要
本文用连续化理论推导出了平面预应力索-拱体系在局部均布荷载下的内力和位移的计算公式,并应用此公式解决集中荷载作用于索-拱体系任意位置的内力和位移计算问题。理论计算结果与试验符合较好。
Formulas for forces and deflections of the cable-arch system subjected to local uniformly distributed load are derived based upon continuum theory. These formulas can also be used to the case of concentrated load by reducing the loading area of the uniformly distributed load to a reasonable small section.Theoretical results are well verified by experimental measurements.
