橫木紋壓力 的英文怎麼說
中文拼音 [héngmùwényālì]
橫木紋壓力
英文
compression perpendicular to grain-
Simplified result of earthquake effects indicate that earthquake resistant capacity are obviously scarce and need to be reinforced. secondly, combining with the timber one - dimensional structural characters, the dissertation bring forward the technology that gfrp stick and steel bar reinforce the timber members whose compression perpendicular to grain have excess load and discuss the craftwork how to do the reinforced members
針對木材橫紋局壓的受力特點和加固目標，本文提出「插筋法」增強古建築木構件的橫紋局壓承載力的技術，研究增強機理和加固后的力學性能，探討製作工藝及在應縣木塔中的應用問題。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。The key technologies that control wooden pagoda vertical compressive deformation were conducted. for the members that have high damnification and were lacking of bearing capacity need be replaced. northeast larch that has high strength and corrosion resistance is the prime timber, but this timber is easy to crack, so their crack resistance need studied
分析發現，木塔底部幾層普拍枋和梁? （柱腳下的橫梁）的橫紋局壓抗力作用效應比最小的僅有0 . 24 ，勢必產生過大的變形，是引起木塔高度降低的主要原因，也是木塔當前最大的安全隱患。
