Analysis on the treatment of empty concrete cracks in the Beijing-Hangzhou Grand Canal expansion project

Based on rational constitutive model of steel and core concrete, the present study is an attempt to investigate the behaviours of box-hollow SRC members subjected to torsion.

Updating coupling method of hydration heat temperature damage for concrete box girder;

Analysis and field measurement of concrete box girder bridges for shrinkage and creep effects;

Numerical assessment for laying-curing project of concrete box girder;

Observation and research on temperature distribution in concrete box girders;

Research on concrete box girders temperature stress;

Aimed at the unreasonable calculation methods for cantilever slabs of concrete box girders,based on FEM and some kinds of calculation methods,a analyses is performed by sub-model technique to study the influence of several parameters,such as distortion for box girders,length and degree of slope for cantilever slabs as well as load location.

3-D thermal stress computation method of highway concrete box-girder;

On several measures for winter construction of prestressed concrete box-girder

This paper introduces a method of simulating temperature distributions in concrete box-girder, which bases on weather information and uses the general finite element program of ANSYS.
