Based on the longitudinal flexural failure tests for a 30-m span PPC hollow plate beam supported by three bearings,the failure modes and ultimate carrying capacity of the beam subjected to concentrated load at midspan are studied.
通过对三支座30 m PPC空心板梁进行纵向受弯破坏试验,研究其在跨中集中荷载下的破坏形态和极限承载能力,认为采用三支座形式对梁的极限承载能力和抗变形能力无明显影响,其强度和刚度能满足设计要求。
