CIVE 420 Final, Spring 2010

Problem No. IV (35%) (Learning Outcomes 7/8) Given a continuous two span one-way slab having a span Jength of 6.0 m each. Superimposed 4 = 550 kg/m”; f'e= 280 kg/em?; and f= 4200 kg/cm’. dead load W sup erimpose: ASSUMING SHEAR STRENGTH-AND DEFLECTION ARE ADEQUATE. J. Assume the stab is 20 cm thick solid slab, and the flexural reinforcement is composed of T20@20cm top reinforcement and T16@20 cm bottom reinforcement applied throughout the span length (along the whole span lengths). If you were consulted to advice on the maximum service live load Wy, in T, /n* that the slab can support to satisfy the ACI Building code requirement for flexural strength, what would your estimate be? (Learning outcome 7)(18 points} If the slab in Q. ] tums out to be a 25 em thick Hourdis slab in which the flexural yeinforcement is composed of 2T20 mm top and 2T16 mm bottom bars per one rib, also applied along the ful] lengths of the spans, what would your estimate of the maximum service live load Wy; in Tim’ be, again to satisfy the ACI Building code for flexural strength?
