定的作用 . 結論 : 以上述的發(fā)展作為基礎 ,我們能夠得出以下的結論 : 1. 直接控制破壞法 (DDCM)這個新的結構設計方法在本文已經被提出 .這個方法較任何一個現存的結構設計方法來說可以更好的以一 種直接的明確的的方式確定和控制破壞的數量 . 2. 這里所介紹的方法是被應用于由混凝土或者石料組成的承受靜力荷載的梁結構 .這些靜力荷載在構件當中會引起軸力和彎矩等的內力組合 . 3. 應用這個方法 ,在計算機軟件和設計圖表的輔助之下設計者可以對一個已知截面形狀與荷載的構件確定其破壞程度 .或是已知最終的破壞水平以及荷載確定截面的大小 .或是已知構件和最終破壞水平來確定最大荷載值 . Direct DamageControlled Design of Concrete Structures Gee D. Hatzigeiou1 and Dimitri E. Beskos, Abstract: The basic methods of structural concrete design that have been developed so far cannot directly control damage, either at the local or the global level. In order to develop an integrated scheme for direct damage control during design and study its application in practice, a new design philosophy, named direct damage controlled design, is proposed. In spite of the generality of the presented design philosophy, this paper focuses on the beam type of structures posed of plain concrete or other quasibrittle materials, such as masonry or ceramics, and subjected to statically applied loading. The proposed methodology appropriately bines codebased stressstrain relations with a simple expression for damage to determine with the aid of the fiber model and the finiteelement method axial force and bending moments of a beamcolumn element as functions of deformation and/or damage.
