This paper investigates the influence of soil-structure interaction (SSI) on seismic responses of long-span space truss roof. First, a three-dimensional (3D) integral finite element (FE) model of a typical regular pyramids space truss structure consisting of space truss roof and support columns is developed. By applying FE method for near field soil and infinite element (IE) method for far field unbounded...
By employing the residue polynomials, we give a construction of constant-composition codes. This construction generalizes the one proposed by Xing (2002). It turns out that when d=3 this construction gives a lower bound of constant-composition codes improving the one by Luo (2003) for some case. Moreover, for d > 3, we give a lower bound on maximal size of constant-composition codes. In particular,...
