A beam subjected to weather upon concrete pouring has a dimension of approximately 310 mm by 555 mm which is reinforced with 4-028 mm bars for tension laid in a single layer with Ø10 mm for stirrups. Determine the following if the concrete compressive strength is 30 MPa and the steel yield strength is 415 MPa. a. Are there any code provisions violated by the actual beam if it is assumed to be singly? State the provision that has been violated. b. If the beam violated a code provision, redesign a smallest single layer singly reinforced beam using the moment capacity of the original beam. (Use same parameters such as dimensions, main bar diameter, stirrups diameter, concrete compressive strength and steel yield strength). c. Redesign a smallest single layer singly reinforced beam using the ultimate moment capacity of the given beam corrected for its violation of the code. (if there are any violation)
