Experimental Study on Structural Behavior of Steel Frames in Building Fire

摘要

References(6) Cited-By(1) About 13 experiments were made with model steel-frames of three stories in which one girder, one column or both girder and column were heated to elevated temperatures at a constant heating rate by an electric furnace. These experiments made it possible to analyze thermal stresses within the steel-frame. Large thermal stresses appeared in the frame corresponding to the "binding modulus" of the frame. The structural behavior was influenced by the thermal stress generated by the heated girder more than by that of the heated column. In addition to buckling of the heated column occured.
