Analisa Kekuatan Tarik Dan Struktur Mikro Dari Baja Konstruksi Bangunan Terhadap Perubahan Temperatur
Besides beauty and freshment there is other factor which very become priority from someone in memanfaatkan a building, good that house, white colars and also other bustle center. The factor strength from the building this research will analyse interesting strength and micro structure from building steel to change of temperature. Analysis (done/conducted) to U iron 40 by using strength K concrete 225. In this research is (done/conducted) examination network that is: Heatreatment, Metalografi Test and Tensile Test. Each; Every this examination is supporting each other result of research, first step spesimen cor first with concrete by using K standart 225, later;then heated in stove with temperature 600 oC refrigeration of air, 600 water quenc media oC, 700 quenc media oC irrigate and 800 quenc media oC irrigate afterwards continued with metalografitest and is last test tensile From result of examination obtained result that temperature 600 [(fire/ burning) temperature] nature of mechanic from spesimen do not experience of change of which signifikan and this (fire/burning) case of U iron 40 can be re-used pursuant to nature of its mechanic.
