摘　　要：在混凝土受压构件损伤演化过程中,各组分之间表现出强烈的非线性相互作用.在这一过程中,裂纹由最初的随机分布状态向将要发生破坏区域集中演化,表现出从无序到有序演化的现象,具有明显的自组织特征.根据混凝土受压构件的自组织特性,建立其损伤演化的序参量方程,求出定态解和非定态解,对混凝土受压构件损伤协同演化机理进行讨论.When the damage of concrete compression members is done, the components of the concrete nonlinearly interact and the cracks randomly distribute. As the concrete members bear the load, distribution of cracks centralize in the destroy area from disorder to order, so it implies that the concrete damage is a self-organization course. According to the proceeding reason, order parameter equation is found and the steady-state solution and non-steady-state solution are analyzed. The synergetics damage mechanics of steel reinforced concrete compression members is discussed at the end of the paper.
