Shallowfoundations on the weak soils result in low bearing capacity and/or excessivesettlement problems. This can cause structural damage, reduction in thedurability, and/or deterioration in the performance level. Some of the soilimprovement methods are to replace the weak cohesive soil by a strongergranular fill or to increase the dimensions of the footing, or a combination oftwo. Recently, the use of reinforced soils under the shallow foundations hasreceived considerable attention. The beneficial effects of reinforcements infoundation applications have been studied by several investigators. Inaddition, the use of geosynthetics under foundations is an innovative andalternative way of absorbing the seismic energy and mitigate excitationstransmitting to upper layers of soils and foundation of overlying structures.This comparative study presents the results of numerical simulations of mediumrise buildings on unreinforced and reinforced sand foundation to investigatethe effects of earthquake characteristics and reinforcement length to mitigatethe earthquake hazards of medium-rise buildings. Various reinforcement lengthsin terms of foundation length “B” have been decided. The study has been carriedout by using a finite element code, PLAXIS 2D. Numerical results revealed thatthe geosynthetic-reinforced sand is quite an effective method to mitigate theseismic performance of the mid-rise buildings and earthquake characteristics inaddition to the reinforcement zone play a very important role by means ofseismic performance.
