Seismic Behavior of Building Frames Considering Dynamic Soil-Structure Interaction

The seismic excitation experienced by structures is a function of the earthquake source, travel path effects, local site effects, and soil-structure interaction (SSI) influences. The result of the first three of these factors is referred to as ''free-field'' ground motion. Structural response to free-field motion is influenced by SSI. In particular, accelerations within structures are affected by the flexibility of foundation support and variations between foundation and free-field motions. Consequently, an accurate assessment of inertial forces and displacements in structures can require a rational treatment of soil-structure interaction effects. In the present study, in order to depict these effects on seismic response of moment resisting building frames, a ten storey moment resisting building frame resting on a shallow foundation is selected in conjunction with three soil types with shear wave velocities less that 600m/s, representing soil classes building frames increase relatively. In brief, the conventional elastic and inelastic design procedure excluding SSI is not adequate to guarantee the structural safety for moment resisting building frames resting on soil classes D e and E e .

“…The foundation is only modelled in direct and equivalent spring-dashpot methods which its geometrical properties are designed based on each model ground condition. In this study, the properties of foundations designed in Tabatabaiefar and Massumi (2010) study are used. The foundation types are considered mat on soil type IV and strip footing on other soil types.…”

“…Arefi (2008) studied elasticity of foundation and soil effects on frame structures and concluded that using elastic base in analysis reduces structure response and destruction effects in joints. Tabatabaiefar and Massumi (2010) studied soil-structure interaction effects on reinforced concrete moment frame structures using numerical analysis with linear behaviour of foundation and structure in direct method of analysis. They concluded that considering soil-structure interaction for buildings higher than seven stories on soil type III (175 < V s < 375) and for buildings higher than three stories on soil type IV (V s < 175) is essential.…”

Abstract:There is no general criterion to determine the necessity of considering the soil-structure interaction in codes. In this study, the effects of considering soil on seismic response of structures are assessed by direct and equivalent spring-dashpot methods. The moment frame structures with three to ten stories located on different soil types are analysed. The results show that considering soil-structure interaction in some models causes an increase and a decrease up to 2 times and 0.6 times in storey shears, respectively. The maximum increase is related to ten-storey buildings which are located on soil type IV and the maximum decrease is related to three-storey buildings which are located on soil type II. Also, considering the soil-structure interaction increases the structure principal period. Finally, a new criterion for determining the necessity of considering soil-structure interaction is presented. In the criterion the soil type, shear wave velocity, natural frequency of structure and building height are considered.

Abstract. Recent studies have shown that the e ects of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and the neglect of SSI in analysis may lead to an un-conservative design. The objective of this study is to simulate the performance of multi-storey building-foundation systems through a Winklerbased approach. Four typical steel Moment-Resisting Frame (MRF) buildings on three soil types with shear wave velocities of less than 600 m/s subjected to actual ground motion records of varied hazard levels are modeled with and without SSI. It is observed that the performance level of models supported by exible foundation, particularly in an intense earthquake event, may alter signi cantly in comparison to xed-based structures. Moreover, for MRFs on soft soil, the nonlinear foundation is found to have a signi cant e ect on the force and displacement demands. This indicates the necessity for consideration of exible foundation behavior in the modern design codes in order to accomplish a more economic yet safe structural design.
