( Shanghai Investigation, Design & Research Institute, Shanghai 200434, China)Abstract: A combining method of new and former structures and their joints are illustrated through discussing ways to build basement in an existing building. In consideration of the existing base being loaded together with the new base slab, the distribution of subgrade reaction was analyzed under the rule of deformation coordinated, to explain that the integrate of basement construction and foundation rebuilt would increase bearing capacity of the bases as a whole. It also proves the necessity to unload existing building at the beginning of construction. Finally some proposals for strengthening and reconstruction works are provided.
Keywords: basement added in existing building; full base slab; deformation coordinated; joints construction, strengthening and reconstruction proposals
