Based on the investigation and statistical analysis of live load during construction spot observed from Xiangyin Bridge, the chang ing law of construction live load of main beam with varied cantilever length is studied.

With on-site measuring data, authors used effective bearing area of members as statistical objects, calculated statistical parameters of live construction load of concrete buildings, referred domestic and foreign achievements, and provided advice about live construction load per effective bearing area of members.

In addition, from construction load, problem of strength, displacement of steel bar and other problems related to structural theory discussion is made in order to ensure engineering quality.

The research of level construction loads influence in super high-rise frame and tube structure;

Study on effect of construction loads on longitudinal deformation of adjacent metro tunnels;

The model of one dimensional consolidation of layered systems is used with,construction loads taken into consideration,but it is difficult to calculate the basis equations from this model.

The emulation analysis of high building by using space structure model possessing conversion layers under constructing loads;

Emulation analysis is made on the high building by using space structure model possessing conversion layers under constructing loads and the calculation model is compared with the traditional method without considering the constructing process.

Research on methods of managing various factors affecting construction activities and time limit responsibility with factor analysis method;
