It is a general measurement to use the"typical equation"for either the force or the translocation when counting the statically indeterminable construction internal force in abutment remove,thus it makes the counting more common and regular.

Theoretical analysis of the beam with fixed joint ends as the simply supported beam;

General solution method of rectangular plate bending with two opposite ends supported under boundary displacements;

Using the united method in this paper,bending solution of rectangular plates with various supported conditions is solved when the plate is subjected to boundary displacements.

Combined with the construction of the Magong Bridge in Changzhou City, the prestress technique by means of the support displacement method to avoid cracks in floor deck concrete caused by tensile stress is studied.

The influence of support displacement on the load\|carrying capacity of arched corrugated metal roof(ACMR) is evaluated through global stability analysis of this kind of roof structure working together with its supporting structure.

This paper analysing a software by the aid of SAP2000 finite element method,adopt 3 kinds nonlinearity link element in common use to carry out a simulation to the sliding bearings on continuous girder bridge(teflon bearing):Level nonlinearity spring element、Wen plasticity element and sliding board element.
