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. Five haracteristic numerical examples are presented to illustrate the proposed methodology and demonstrate its direct applicability to structural design CE Database subject headings: Damage。 Concrete structures。盡管提出的這個(gè)設(shè)計(jì)觀點(diǎn)只是一個(gè)概括，但是本文將重點(diǎn)集中于在靜載荷作用下梁，它由素混凝土或者其他
