Abstract/Summary In present study, a full-scale testing of reinforced concrete (RC) frame sub-assemblage has been investigated under fire subsequent to simulated seismic loading. The RC frame sub-assemblage was designed for 60 minutes fire resistance per relevant Indian code. First part of the sequential loading consisting of a quasi-static cyclic lateral loading on the test frame so as to provide a reasonable simulation of the damage expected to occur under real seismic loading. The quasi-static lateral loading history of the frame sub-assemblage corresponds to life safety level of structural performance. In the second part of the rest, a compartment fire was ignited to the pre-damaged test frame was instrumented exhaustively with sufficient numbers of different types of sensors. The first cracking was observed at the end joints of the roof beams after the frame experience a 30 mm cyclic lateral displacement. After the mechanical load test, the RC frame was exposed to one hour compartment fire. One hour heating and eleven hour cooling was tracked and temperatures were recorded. A knocking sound was heard from the fire compartment after the fire ignition which could be attributed to the spalling of concrete from the roof slab. Severe thermal micro-cracks, massive spalling with exposed reinforcement in roof slab and excessive degradation of the concrete at a number of locations of the frame sub-assemblage were observed during visual inspection after the fire test. The test results developed understanding of the behaviour of RC frame sub-assemblage in FFE.
