Problem 1: The frame shown represents the front part of a simple one bay structure in North York. The structure comprises a floor slab monolithically connected to the longitudinal and transverse beams. The structure is to be designed for snow, self-weight, and an earthquake force accounting for 12% of the building weight acting at the center of mass (slab center). Find the design values for ULS (moment, shear and axial load) of the column at the base, at the beam ends and at the beam midspan. Provided are the typical moment diagrams for a portal frame under various load conditions.
Slab thickness = 200mm; Beam web: height = 600mm: depth = 300mm; Column = 400x400mm building height = 3m (to slab top)

Problem Two: The beam shown below part is for an interior span and is cast monolithically with a one-way slab. The clear span for the beam is 30 feet, and the clear spacing between beams is 10 feet. (a) Reinforcement is shown for the positive moment region. Determine if the beam is adequate to support a uniformly distributed, factored load of 5 k/ft. (b) Design the slab reinforcement for the positive moment region using a factored load of 500 psf....
Q2: An office building of simple construction has a constant bay width of 12 m in the longitudinal direction. In the transverse direction, the column spacings are 4 m followed by 3 m. Assuming that the slab spans one-way, calculate the moments and forces required for internal longitudinal beam design.

Questions 5-8 A steel frame shown below is subjected to combined uniformly distributed gravity load (w 2 kips/f) and a horizontal earthquake load of H-10 kips Both the beams and the columns are made of W12x120 section having a yield strength of F 45 ksi. The Young's modulus of steel s E-29,000 ksi. The distributed load w is used to simulate the self-weight of the beam, the load transferred from roof slab, as well addition superimposed dead loads. The self-weigh...
Problem 22. Two-story, one-bay unbraced frame shown below is subjected to gravitational dead and live loads and wind lateral load. The columns are made of W18x65 (I,-1070 in , Ag- 19.1 in2, r-7.49 in, ry-1.69 in) and beams are made of W18x71 (1, 1170 in). The table below shows the moments at the ends of column 4-5 due to three load cases. The frame is fully braced in lateral direction. Use Grade50 steel Bending is about strong axis. All gravity...

Q1. A continuous one-way slab is subjected to Gu(including self-weight) - 7.0 kN/m' Q-4.5 kN/m2. At the exterior ends, the slab is cast monolithically with the edge beams. Assume C30/37 concrete, grade 500 steel, and 25-mm cover to bars. Size of each beam is 350mm x 450mm, size of each column is 400mm x 400mm. (a) Determine the slab thickness. (b) Check whether the design shears and moments at critical sections (e.g. at mid- spans and supports) can be determined...
The following figure 1(a) shows a part of a reinforced concrete building in a school. The structure consists of precast concrete hollow slabs that rests on the 10.8m long two reinforced concrete beams. The beams are supported on reinforced concrete columns. It is given that, on the top surface of the hollow slab, there will be a concrete screed with 50 mm thickness (assume density of concrete screed is 25 kN/m). In addition, there will be tiles that weigh 0.05...

How do I solve this? Problem 2(50 points) The roof of the Edwin A. Stevens building is to be redesigned to accommodate a billboard for Stevens Institute of Technology. The new billboard will weigh 40 kips and be supported equally by two columns located 9 ft from the rear of the building. The beams supporting the new roof will be simply supported as shown. (Note there is a 5 ft overhang at the front of the building). For the grade...
