Problem Statement- Given the Simply-Supported Beam shown below with: - Service DL = 24 kN/m including the self-weight of the beam & Service LL = 16 kN/m Span of the beam is 7.5 m to the center of the columns (columns are 0.5 m x 0.5 m) Top, bottom, and side covers to center of steel = 50 mm The beam cross-section is rectangular with b = 350 mm & total depth h = 550 mm Reinforcement is 5 ¢ 25 at the maximum moment location Compression steel 2 o 19 (top cover = 50 mm) Use f' = 21 MPa & = 420 MPa SLL = 16 KNm SDL = 24 kNm 7.5 m (1) Check if the flexural Strength is adequate: analyze as doubly-reinforced beam be (2) Design the beam for shear and show you final design details neatly; use o10 stirrups ( (3) Calculate the required development length of the No. 25 bars (the bars are not epoxy-coated, normal weight concrete, take (Ctku da) = 2.0, & then check at what location from the beam centerline 3 of the 5 bars can be cut-off (4) Calculate Ie & and check if the floor beam meets the ACI immediate LL deflection criteria
