Title

Permanent Excavation Interaction and Adjacent Building under Earthquake (Case study: Entrance Ramp of the City Train and Hamyari-Shahrdari Building)

Pages

  57-70

Abstract

 Deep excavation have a direct effect on stresses and strains of surrounding soil, and it leads to the change in static and Dynamic response of adjacent structures of the excavation. In this study the effects of urban rail ramp permanent excavation on Hamyari response, has been investigated. Consideration of soil-structure-groove interaction has a great effect on the structure response, including increased range of internal motion of foundation and floors, reducing the Base shear, and increasing the natural period of the structure. The three-dimensional study has considered a nonlinear behaviour for soil and steel materials and also, semi-infinite elements have been used for viscose boundaries. The use of semi-infinite boundaries has shown a desirable performance in seismic analysis of soil environments. Placement of the building near the entrance ramp of Kermanshah metro and consideration of Soil-structure interaction near the excavation, lead to the 8. 98% increasing in the first period of the structure, decreasing 19. 37% Base shear of the Structure against the rest rigid condition, and also increasing the lateral displacement of floors, especially higher floors, and this increment in the roof floor compared to the rigid base and Soil-structure interaction are 89. 89% and 14. 25%, respectively. Also, consideration of Soil-structure interaction adjust excavation for building compared to the case with soilstructure interaction and without the excavation effect, leads to the 1. 09% increasing in the first period of the structure and 10. 27% decreasing in Base shear, and also increasing of acceleration response spectrum.
