| Research Abstract |
Fire response analysis is important on the study of fire resistances of building frames in steel, since the high thermal stresses could not be evaluated correctly by means of only experimental or purely theoretical considerations. However, increasing computational needs imposed to the fire response analysis and according ever expanding computer code are going to lower the productivity of the computer implementing works. The key points letting a program highly general purpose seem to reduce every individual computational need to an independent component and simultaneously to maintain the robustness of the entire code against adding, deleting, and exchanging the developed components at any level of the code structure. A new and experimental C++ program has been developed to this end, which enables one to conduct a wide variety of fire response analyzes. The following software skills are developed and implemented in the program.
1) Keyword utility has been developed and implemented, which makes any individual component highly modular.
2) A new input utility has been developed which makes input files more readable and simultaneously makes an input code simpler. Docking both developed utilities provides an easy input environment where the input files acts as if it were a logical programmed code controlling completely all the variety of actions of the fire response analysis.
