Abstract: In the present study one type of interaction phenomena arising between adjacent buildings was studied. The problem of load-burdening of a building due to a vertical displacement of the basement of the adjacent building through frictional load-transferring mechanisms was studied. This problem can be formulated in the form of a Quadratic Programming Problem (QP), which can be solved by any available QP algorithm. Numerical experimentation on the problem revealed the physical mechanism in this case and permitted us to discuss certain aspects on it.
