Name: Date: Part II: Numerical responses 1. (+35) Design a rectangular reinforced concrete beam (tension steel only) for a simply span of 30 ft. Uniform service loads are 2 kips/ft dead load (included the beam weight) and 3.0 kips/ft live load. The beam is to be not exceed 16 inch wide due to column size. Use fe'=4000psi and fy 60000psi. Sketch your design and calculate Mn for the beam you design. Note: this is an open-end design for you to...

A rectangular, tension-reinforced beam is to be designed for dead load of 500 Ib/ft plus self weight and service live load of 1200 Ib/ft, with a 22 ft simple span. Material strengths will be fy 60 ksi and J 16 in. Calculate the required beam width and tensile steel requirement, using a reinforcement ratio of 0.60po.o0s. Use ACI load factors and strength reduction factors. The effective depth may be assumed to be 2.5 in. less than the total depth steel...
