Resist Fire Theory And Calculation Study For Prestressing Force Grid Structure

This text has carried on the analysis of resisted fire ability to the prestressing force net frame at original fire model theory with the foundation of now available prestressing force steel structure standard . Uses the program of establishment to have imitated the destruction state that the prestressing force net put up under the different temperature , thus the prestressing force nets the fire destruction course putting up to simulation . Moreover still the utilization program has been imitated the resisted fire ability that the ordinary flat board was netted to put up , and analyses prestressing force and nets the resisted fire property putting up by way of the contrast, and has found that the prestressing force dull and stereotypedly nets the resisted fire weakness putting up , for prestressing force nets frame application has created the conditional sum basis that is suitableThree corresponding calculator programs of establishment all use the model have been verified their correct nature . The living example model has used the trial model of reality , thus for the initial stage calculation data has provided effectively and verifysThis text is aimed at giving an economy practical virtual reality method and the train of thought to the resisted fire research aspect of prestressing force net frame . Imitate prestressing force net the corresponding change under the different temperature of frame by way of the calculator program , and reflects the fire prevention property of prestressing force net frame on the fixed level .
