The ABAQUS Analysis Of The RC Frame Structrue For Anti-progressive Collapse

The property of reaction to normal load on the structure has been researching and developing for many years,which could satisfy the need of feliability of structure.But the accidental load to the structure usually be neglected and once it happed,it may lead to the progressive collapse of structure.For example,the strike of car,terroristic attack,the explosion of bomb,and so on.From the explosive event that the Ronan Point apartment in1968,all of the world first research the progressvie collapse of structure.And after the event "9.11",the discussion of the progressive collapse of sturcture come to the climax.Many countries also establish the relative norms.For example,DOD2005,GSA2003, and so on.These structure which have been designed by them behave the favorable property in the event.The text researches the mechanism when the accidental load act on the structure and analyzes the reaction when it is on the different anti-earthquake level,different earthquake intensity,different destroyed column.It could afford the proof for design of anti-progressive collapse.The important content as follows,(l)By reading many former literatures and analyzing the relative circs at home and abroad, it desides what to write.(2)It particularly expatiates the norms of all the counties to anti-progressive collapse and get the conclusion of analyzed method,calculated formulation.By summing up the content,it get the differences and importance of them.(3)It expatiates the research method and designed method of progressive collapse of structual so that analyze the merit and shortback of them and which to suit.And importantly analyzing the non-linear and big distortion on the structure in the text,which is different from normal method.(4)Analyzing a practial frame structure of3story.Using PKPM soft calculates the structure to get the reinforcement situation and put the load, reinforcement situation, material performance into the ABAQUS soft.By the element of model change of the coner column,border column,long middle column,short middle column to get the distortion and reaction of structure and estimante whether it will collapse or not.Then,changing earthquake intensity and repeat abored-metioned content.Finally,it will get the conlusion that the different earthquake intensity may affect the progressvie collapse of structure by analyzing the calculated result.
