【導讀】圍內(nèi)都還不能直接控制破壞。為了形成一個綜合的方案以便在設(shè)計期間對直接破損進行控制。并且在實際中對其應(yīng)用性進行研究，一個名為直接破損控制設(shè)計的設(shè)計觀點被提了出來。凝土或者其他的準脆性材料，比如砌塊，水泥等組成。這個提出的方法適當?shù)慕Y(jié)合了基于規(guī)。結(jié)構(gòu)中的破壞狀態(tài)時,在設(shè)計的過程中以上的這些術(shù)語應(yīng)該被清楚的定義.為了滿足安全的要求,出現(xiàn)了三種不同的設(shè)計理論,從而推倒出了以下的設(shè)計方法.的位移進行檢查.因素起了決定的作用.荷載在構(gòu)件當中會引起軸力和彎矩等的內(nèi)力組合.和最終破壞水平來確定最大荷載值.
【正文】 lacement or interstory drift between two successive floors on a multistory building during an earthquake (Priestley 1997).These limitations on displacements lead to an appropriate stiffness of the structure and consequently the necessary internal forces for the dimensioning of structural members. Thus, displacements here play the fundamental role in design, in contrast to the USM, where this role is played by forces Conclusions On the basis of the preceding developments, one can draw the following conclusions: 1. A new method of structural design, the direct damagecontrolled method _DDCM_ has been developed in this paper. This method quantifies and controls damage in a direct and transparent manner much better than any of the existing methods of structural design. 2. The method has been illustrated here as applied to the case of beam structures made of plain concrete or masonry and subjected to a statically applied lading that creates axial forcebending moment load binations in their members. 3. Using this method, the designer can determine the damage level for a known shape section and loading, or dimension a section for a target damage level and known loading, or determine the maximum loading for a known section and a target damage level, with the aid of either a puter program or design charts
