Fireproof Design And Computation Of Reinforced Concrete Component

Fireproof design and computation of reinforced concrete component is researched in this thesis.Till today,there are no interrelated fireproof standards about buildings built in china. In general,fireproof design is considered by architects not by structure engineers. After fire,we compare the fireproof time of the component with the fireproof limit supplied by standards to design. These means are all based on experience and test. In the thesis,we make fireproof design through calculation.According to the existed original data,the test result and standards built in other countries,some mechanical capacities of steel and concrete are given in the thesis. So,interrelated diagrams and formulae about the discount coefficient calculation of strength are earned.The standard is proposed to verdict the limit state of fire-suffered reinforced concrete component in the thesis,that is,losing stability,integrity and thermal insulation,and limit state of load bearing capacity is mainly discussed. In the thesis,two dimensional non-stable conductivity is researched in detail,with the consideration of the influence of variable capacity. We established model of temperature computation in use of difference. According to the models,the programs are organized to implement the simulation by means of software-VB. So the load-bearing capacity of fire-suffered reinforced concrete components is computed obviously.The experimental data are used in order to compare with simulation result. Therefore,the practicability of computation method and the simulation methods in thesis is verified.The strengthened methods and the computation of strengthened quantity of fire-suffered component are given in the thesis. In the actual construct,the component is strengthened according to the strengthened quantity,it has some leading signification to acertain extent.
