PROBLEM 1: The continuous floor beam ABCD is shown in the figure. It has a 100 mm slab thickness and the beams bxhis 300 mm x 500 mm. Column section is 0.30 m x 0.30 m. Live load = 3.6 KPa Superimposed Dead load = 2.6 KPa Concrete weighs = 24 KN/m L= 8 m. S= 2.8 m. 28 neglect the live load Reduchion O Compute the positive moment for beam EF. 2.8 8 m 8 m 8m O Compute the negative moment at the face of support E OCompute the negative moment at F

As shown in the figure, a 3m-long cantilever beum is subjected to a uniformly distributed dead load, we-1.S t/m. It is know that f = 20MP. fy =420 MPa, and 4, = 1800 mm. Please find the maximum allowable uniformly distributed live load, wt is assumed that the unit weight of concrete is we24 t/m. -300m-

A rectangular reinforced concrete beam has a length of 14 m is simply supported atboth ends. The width of beam is 350mm and the overall depth is 550  mm. Determine the area of the steel reinforcements if the beam is to carry a DL = 15kN/m and LL =18kN/m. The concrete strength fc = 25  and steel yield fy = 400 ������. Use 60 mm concretecover.
