Multiple Cross-Laminated Container Floor Temperature Field Based on ANSYS

Abstract:

Concrete composite beam floor cage floor as a new form , with a saving of steel and concrete , lighter weight, the advantages of high capacity , and has been more widely used in engineering. Therefore , to carry out the new concrete composite beam floor cages fire behavior for large spaces , large span areas is necessary. This article is the use of finite element software ANSYS multi-span composite floor beams cages fire tests to simulate life and death through SOLID70 unit features analog composite bottom plate before and after bursting floor temperature field and gives composite floor box overall temperature distribution along the rib cloud cover and the temperature of the beam cross-section of different heights - time curve , finally, the simulation results and experimental conditions were compared and analyzed , the main draw the following conclusions : the use of ANSYS thermal unit SOLID70 cell function and death can be simulated temperature distribution in case of fire concrete composite floor beam floor cages before and after bursting through the ribbed section of different heights temperature - time curve can be seen, the test results agree well with the simulation results ; testing process with increasing temperature , floor surface inlets, stacked boxes floor temperature contours directly reflects the law during the test floor surface appears inlets .
