When the factors that will affect the cost of a cement plant\'s storage building (of a double-layer spherical shell structure) are defined, the graph that framework weight varies with support stiffness is programmed based on statistics.

This paper reveals that the apportioning horizontal forces of the piers and abutments are directly proportional to the anti-pushing rigidity of their corresponding compounding pier and abutment.

According to the uncertain problem of elastic support stiffness for complicated space truss in practical projects,which is led by differential settlement of weak foundation,mathematical anti-problem method is proposed,and mathematic analysis models for anti-problem are established.

The effect of pier high and bearing shearing stiffness on the seismic induced behavior of the beam and the pier of model was studied on a shake table by using a continuous beam bridge model polymethyl methacrylate.
