摘要：已发展了的混凝土结构设计的基本方法到目前为止不管是在局部地方还是世界水平范围内都还不能直接控制破坏。为了形成一个综合的方案以便在设计期间对直接破损进行控制并且在实际中对其应用性进行研究，一个名为直接破损控制设计的设计观点被提了出来。尽管提出的这个设计观点只是一个概括，但是本文将重点集中于在静载荷作用下梁，它由素混凝土或者其他的准脆性材料，比如砌块，水泥等组成。这个提出的方法适当的结合了基于规范的应立应变关系.五种特有的数字实例被提出，以次来解说被提出的方法论并且说明对于结构设计的直接适用性.

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 composed of plain concrete or other quasi-brittle materials, such as masonry or ceramics, and subjected to statically applied loading. The proposed methodology appropriately combines code-based stress-strain relations with a simple expression for damage to determine with the aid of the fiber model and the finite-element method axial force and bending moments of a beam-column element as functions of deformation and/or damage. Five haracteristic numerical examples are presented to illustrate the proposed methodology and demonstrate its direct applicability to structural design
