采用经典塑性和连续损伤模型,确定了塑性变形的演化法则,发展了一种基于抗震损伤的混凝土框架结构分析模型。运用两端具有塑性铰的梁模型模拟框架结构的梁柱。算例表明,该模型的损伤指数可以确定结构各单元和整体在地震时的性能及结构极限荷载,具有可靠的精度。
Using classical plasticity and continuous damage model, the evolution rule of plastic deformation is determined, and a kind of analysis model of concrete frame structure based on earthquake damage is developed. Beam columns of a frame structure are modeled using a beam model with plastic hinges at both ends. The example shows that the damage index of the model can determine the performance and the ultimate load of the structure of every unit and the whole structure in earthquake and has the reliable accuracy.
