橫向壓縮應變
英文
transverse contracting strain-
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。Then, a step - by - step increase of vertical curvature is applied to the hull girder assuming that the plane cross section remains plane. at each incremental step, the stress of the cross section is evaluated using the average stress - strain curves of the elements as well as the incremental bending moment due to the curvature increment. performing sample calculations on existing girder models tests under pure bending, the rationality of the proposed method was examined
假設船體橫向框架材足夠強，因而板架的整體破壞不會發生；基於梁?柱理論、理想彈塑性假設、平面假設，建立了拉伸和壓縮加筋板單元的平均應力?應變關系曲線，應用船體結構總縱極限強度的簡化逐步破壞分析方法計算船體總縱極限彎矩，並據此開發了計算程序sus 。
