For tackling the difficult problem of box-girder web crack,coming up with a new strengthening technology Lateral Tension for Vertical Prestress,and then try to do a simulation analysis with the finite element analysis software,checking out the effect and feasibility,find a new way for the long-span prestressed concrete box-girder web crack strengthening.

Ultra-Long Vertical Prestressing Technology;

Equivalent Mechanical Model for Seismic Forces in Combined Tanks Subjected to Vertical Earthquake Excitation

It points out the court vertical design is crucial of slope villa area,which is in relation with the design of other aspects in villa area.

Based on experiments of Pseudo members of RC frame exterior joins under load,this paper comprehensive analyses of the experimental results,and focuses on the 90—degree hooked bar s anchorage performance affected by additional anchorage bars.

For studying the influence of the horizontal inner plate on the static strength of tubular joints,overall 62 T-joint models with and without reinforcements are analyzed usingfinite element method.
