地震工程的性能化设计:发展状况

当前建筑规范的设计目标着重于生命安全,在小震和中等地震下控制破坏,在大震下防止坍塌。然而,为实现这些目标,设计的可靠性是未知的。研究人员和设计人员的共识是将来的地震设计需要达到多个性能目标。未来的抗震设计将以明确的,能够定量的性能指标为基础,需要考虑多目标性能和危害水平。在基于性能设计的程序广泛应用之前还面临一些挑战:在地震工程中,基于性能设计的前景将直接涉及性能目标的界定,一般的设计方法,地面运动模型以及对需求和容量的评估等问题。

Performance-Based Design in Earthquake Engineering: State of Development

The design objectives in current building codes address life safety, control damage in minor and moderate earthquakes, and prevent collapse in a major earthquake. However, the actual reliability of the design in achieving the objectives is not known. There is a general agreement among researchers and professionals that future seismic design needs to be based on achieving stated multiple performance objectives. Future seismic design practice will be based on explicit performance criteria that can be quantifi...
