stiffness criterion 中文意思是什麼
-
Partially prestressed concrete structure has been widely used in the field of civil engineering. the deformation is very important for prestressed concrete members, for they are thinner than those of reinforced concret owe to the adoption of hign - intension material and developed technic of design and construction. at present, there are some formulae for deformation in the criterion of many countries. mostly there are 3 methods in use : double linearity method, method of valid inertia and curvature integral calculus method. this article will discuss the influence of material, spa, construction form, and adjust the formula for stiffness of gb50010 - 2002 to a new uniform formula for deformation
在土木工程領域，部分預應力混凝土結構因其良好的跨越能力和經濟性而得到了廣泛的應用，並發揮了巨大的作用。由於採用了高強度材料並進一步改善了設計和施工技術，預應力混凝土構件一般比普通鋼筋混凝土構件更為細巧，因此，撓曲變形問題顯得尤為重要起來。目前，各國規范對于部分預應力混凝土構件的變形計算均有相應的公式，變形計算的關鍵是剛度的計算。 -
2. a relevant formula of eight - node adhesive finite element is deduced in the paper, which is based on a separately interpolation scheme for reissner - mindlin plate element. a load capability analysis method for patched composite laminated structure is established by using tsai - hill failure criterion and thai ' s reduced stiffness scheme, and corresponding computer code is also developed
在任意四邊形四節點復合材料層合板殼單元的基礎上，推導了相應的八節點膠單元，並採用蔡-希爾強度理論以及蔡氏剛度退化準則，對復合材料層合板膠接補強結構進行剛度分析和極限承載能力分析，編制了相應的有限元分析程序。 -
Combined with a project financially supported by the construction bureau of hunan province, some studies on this floor have been carried out in this thesis. the valuable results achieved are outlined as below : 1. compared with the current concrete criterion, a method for the stiffness of thin - wall core box cast - in - site concrete hollow floor which is analyzed in this thesis is proposed
本文結合湖南省建設廳重點資助項目對薄壁箱體現澆混凝土空心樓蓋進行研究，取得了的研究成果，如下: 1 、對薄壁箱體現澆混凝土空心樓蓋的剛度進行了分析，以《混凝土結構設計規范》為基礎，提出了現澆空心樓蓋剛度和內力的簡化計算方法，其計算結果與已有的試驗結果吻合良好，使樓蓋內力和變形的計算過程得以簡化。
