PENGARUH BENTANGAN DAN KELENGKUNGAN TERHADAP KEKUATAN STRUKTUR ATAP BENTUK PAYUNG TERBALIK

Amin Sumadyo, Hari Yuliarso

Abstract


Research by using scale model good for perceiving structure behavior that happened and also parameter influencing that. Perception to inversed umbrella structure model, relate to hypar roof dimension unfold 5 metre and 7,5 metre with each one prop column, thickly concrete plate 8 cm. Roo dimension this models were made with scale 1/5 from real roof dimension, then both model tested by its strength with flatten beam, till critical phase of strength, in e form of cracking and also fail structure. Through hypar area analysis use membrane theory and ultimate strength theory, yielding behavioral conclusion of hypar area in arrest brittle failure.
