Abstract

Existence of grade demand would better with quicker workmanship time, but expense of cheap peeps out form of ready made concrete (precise) with grade which better guaranteed and amenity in the case of execution. With existence of this research to know direction influence of bone to moment of crack, moment ultimate, burst cupola and plate precise crack length. This research done in laboratory Technology Beton Universitas Muhammadiyah Malang. Execution of This research covers some phases that are: inspection of concrete compiler material and test draws bone steel, casting of plate pracetak, keeping of precise plate with closing wet potting during 28 days and hereinafter is done assaying. Given various direction of bone 90°, 45°, 30° at plate (100x50x8) cm. From result of this research shows direction of bone to plate influences bending moment ultimate. At plate 2 bending moment side of the biggest ultimate is obtained by direction of bone 90° increases 50 % compared to direction of bone 45°. At plate 4 side (direction y) bending moment of the biggest ultimate is obtained by direction of bone 45° increases 24,26 % compared to direction of bone 90°, while at ( direction x) its(the value semi times ( direction y). For rigidity of plate at plate 2 the biggest side is obtained by direction of bone 30°, plate 4 side ( direction y) the biggest rigidity is obtained by direction of bone 90° and (direction x) the biggest rigidity is obtained by direction of bone 45°. At plate 2 burst cupola side happened is in the form of direction parallels length straight of fulcrums. Burst cupola happened at plate 4 side initially is in the form of direction parallels length straight of short side but along of addition of payload, new crack cupola of emerges between cracks which has been formed emerges increase of unidirectional crack with plate length side causing joints between the cracks.
