橫紋壓縮
英文
compression perpendicular to grain-
Yingxian ancient wooden pagoda is a flat - form tall building, which was formed by the superposition of monolayer temples. the height of 67. 31 meters made it encountered two unprecedented puzzles : firstly, with the height increased whopping, wind resisting and aseismatic capability become the main question of the whole structure ; secondly, because of the weight increased unconventionally, members of the lower 1 ~ 3 floors hold overloading perpendicular to grain and they brought large vertical deformation
相對於一般殿堂結構,高度和自重的成倍增加,使木塔遇到前所未有的兩項難題:其一是因自重增加,使承受上層柱軸向荷載的梁(普拍枋和梁? )橫紋局壓應力成倍地超過設計強度而產生嚴重的壓縮變形甚至劈裂,導致木塔整體豎向變位。First of all, the structural characteristic and essential of damages were introduced. secondly the efficiency factor of how much the compression stress perpendicular to grain is more than the design value was calculated. thirdly, the main reason that members were made too large deformation and serious damage was pointed out
但是,目前木塔殘留的整體傾斜、層間側移以及由木材橫紋壓縮引起的豎向壓縮變形等都已達到嚴重影響其安全可靠的程度,所以,木材橫紋局壓增強加固問題亟待解決,以防突變。
