ICreep Failure Analysis Of Marine Concrete

With the development of the marine economy，the use of Marine concrete is more andmore popular. There are a number of coastal provinces, very long coastline and internationalports in our country. Concrete buildings in marine environment play an important role inoperation scheduling and marine port development areas. It also plays an pivotal role inbuilding marine construction under national strategies. The reason why corrosion and fractureof concrete phenomenon more serious is that brine contains a lot of sodium chloride and otherions, which corrosion is serious.It shows that structure damage losses reached to hundreds of billions dollars each yearcaused by environmental corrosion concrete, all over the world. As a result, the study ofconcrete material attenuation law in marine environment, to analysis aging, crack safety anddurability，which is not only a multi-scale, multi-disciplinary problem and important toscientific value，but also contributes to reduce aging and damage in marine structures,beimportant to develop and protect resources in marine.In this paper, it is different types of relationship based on the creep properties in differentperiod and the material characteristics of concrete structure in the marine environment.Combine the theory of elasticity and concrete creep theory to modeling and then, analyze therelationship of concrete creep equation. Collect test data of others to calculate creep modulus byleast square method. using ANSYS calculate concrete-creep for a long time, in order to drawcreep-curve in Marine environment. The next step is comparing it with theoretical analysis ofthe common concrete creep-curve and come to the conclusion, finally.
