Isolation Period

The pounding of retaining walls forms a potential risk of degrading the performance of seismically base-isolated buildings subjected to strong, especially near-fault, earthquake ground motions. Incremental dynamic analysis is employed to generate the so-called gap graph, in which two characteristic gap sizes of a base-isolated building are related with the isolation period of the building and the strengthof the superstructure. Thegapgraph canbe usedto evaluate the required gap size for a base-isolated building to have certain collapse performance. By means of gap graphs, the interdependent relations of gap size with other important factors that influence the seismic performance of the base-isolated building are examined. In particular, the results show that near-fault pulse-like ground motions are likely to impose much higher demand for the isolation gap than far-field ones.

Near Fault

This paper examined the engineering characteristics of the near-fault ground motion. The four-story reinforced concrete frame was designed under Code for seismic design of building (GB50011-2010).The SAP2000 software was applied to model it, and the nonlinear time history analyses of structure were implemented. Near-fault ground motions with forward directivity and fling-step and far field ground motions were selected as seismic inputs．The results show that in terms of some structural dynamic response parameters, such as the vertex displacement, between the corner of the layer displacement, and the base shear et al., the structural responses to the ground motion with near-fault are increased by considerable magnitudes when the seismic responses of structures step into the elastic-plastic stage, compared with far-field ground motion, and the influence of damaging the mid-lower structure is significantly greater.
