摘要：Öz Shallow foundations on the weak soils result in low bearing capacity and/or excessive settlement problems. This can cause structural damage, reduction in the durability, and/or deterioration in the performance level. Some of the soil improvement methods are to replace the weak cohesive soil by a stronger granular fill or to increase the dimensions of the footing, or a combination of two. Recently, the use of reinforced soils under the shallow foundations has received considerable attention. The beneficial effects of reinforcements in foundation applications have been studied by several investigators. In addition, the use of geosynthetics under foundations is an innovative and alternative way of absorbing the seismic energy and mitigate excitations transmitting to upper layers of soils and foundation of overlying structures. This comparative study presents the results of numerical simulations of medium rise buildings on unreinforced and reinforced sand foundation to investigate the effects of earthquake characteristics and reinforcement length to mitigate the earthquake hazards of medium-rise buildings. Various reinforcement lengths in terms of foundation length “B” have been decided. The study has been carried out by using a finite element code, PLAXIS 2D. Numerical results revealed that the geosynthetic-reinforced sand is quite an effective method to mitigate the seismic performance of the mid-rise buildings and earthquake characteristics in addition to the reinforcement zone play a very important role by means of seismic performance.
