Modal Analysis for Building-Soil Interaction. An approximate method of modal analysis is presented for the earthquake response of linear building-foundation systems.

Modal damping is obtained as a formal extension of the classical method of modal analysis and is shown to be equivalent to the energy ratio criterion proposed by Jacobsen.

FEMA (NEHRP recommended seismic provisions for new buildings and other structures, FEMA P, Washington, ) and ASCE (Minimum design loads for buildings and other structures ASCE/SEI /, Reston, ), describe the problem of multi-degree-of-freedom systems with soil-structure interaction (SSI).

Structure–soil–structure interaction (SSSI), put forward in recent decades, means the dynamic interaction problem among the multi-structure system through soil-ground.

Incremental dynamic analysis (IDA) (Vamvatsikos and Cornell, ) is an effective method to evaluate the seismic performance of structures and is widely used in structural seismic research.

To evaluate the impact of the SSI on the collapse resistance of the Shanghai Because of the limitations of testing facilities and techniques, the seismic performance of soil-structure interaction (SSI) system can only be tested in a quite small scale model in laboratory.

Especially for long-span bridge, a smaller tested model is required when SSI phenomenon is considered in the physical test. The scale effect resulting from the small scale model is always coupled with Efficient modal analysis for structures with soil‐structure interaction Efficient modal analysis for structures with soil‐structure interaction Wu, Wen‐Hwa; Smith, H.

In a new complex modal pushover analysis developed in this study, the seismic demand for each mode is determined by regular pushover analysis method using modified modal inertia force distributions.

The response of some structures is dominated by inertial interaction (e.g., T ˜ / T ≈ 4, ζ ˜ 0 ≈ 30%), whereas others undergo negligible soil-structure interaction (e.g., T ˜ / T ≈ 1, ζ ˜ 0 ≈ 0). Simplified analytical formulations described in the companion paper by Stewart et al.
