The failure often happens due to roof cladding failure . the explanation of this phenomenon is that some roof cladding zones susceptible to wind load have not been strengthened to resist wind load . when the typhoon makes a surprise attack on the low - rise buildings , those zones failure happens ahead of the whole cladding failure caused by roof cladding failure 風(fēng)災(zāi)后有大量的低矮房屋的維護(hù)結(jié)構(gòu)遭到了破壞,且大多源于屋面結(jié)構(gòu)的破壞,其原因是屋面結(jié)構(gòu)的薄弱部位沒(méi)有加強(qiáng)抗風(fēng)處理,臺(tái)風(fēng)襲擊過(guò)程中往往這些薄弱地方先行破壞,導(dǎo)致整個(gè)維護(hù)結(jié)構(gòu)破壞。
