On the basis of the strut-and-tie model for prestressed deep girder and on the principal of local analysis of structure,this paper makes a study of and proposes a local analysis method of the strut-and-tie model for prestressed continuous girder with its local part equivalently transferred into the prestressed deep girder.

In this article the local analysis of steel-concrete combined sections in a composite cable stayed bridge with single tower and double cable plane is carried through as an example,which is the No.

According to the complexity and particularity of the project, this paper presents a finite element method of both global analysis and local analysis for the airport building of Beihai.

After analysising, presents a check method which is based on the "partial analysis", this method can accomplish the small dirt check very well.

In addition,establishment of finite element model for a complicate bridge,simplification for a longitudinal steel-box girder,disposal technique of partial analysis for complicated connection and .

A new method named local analysis method is first presented and adopted where the whole structure is divided into two parts: the upper structure and the lower structure.

The time series of fluctuating pressure signals under different experimental conditions were measured by a pressure transducer,and a novel method for measuring gas holdup in bubble column was proposed,namely,the local gas holdup was estimated by resorting to local intermittency measurement(LIM)method and multi-resolution analysis of the time series of fluctuating pressure signals.
