Assembly contact analysis of the sheet rolling mill′s prestressed stand;

A new pattern of support technology of prestress trusses was expounded in detail,including its conception,mechanism,advantages as compared to anchor cable,forms,and construction technique.

The secondary moment of prestressed concrete frame is different from that of continuous beam.

The moment modulation of prestressed concrete frame has some differences compared with that of continuous beam.

In this paper, based on the structure characters and load applying means, a method called as curvature force method is put forward and proved in the nonlinear analysis of bonded prestressed concrete frame.

The mechanics analysis of prestressed frame during the construction process under difference construction method;

In With one-storey,two-span prestressed frames,a comparative study is done between under vertical and horizontal loads.

By the experimental study on a full-dimensioned prestressed frame of two spans, the relative factors are analyzed such as relative height of equivalent compression zone in critical section, secondary moment, ratio of beam rigidity to column and development of cracks in the top of columns etc.
