- Find the value of maximum load P sothat the stresses in the frame illustrated willnot exceed 120MN/m2 in tension or 90MN/m2in compression.The bars of the pin-connected frame shownhave a section of 35mmx65mm each.Design the spacing of the main bars and temperature bars of a one-way slabhaving a total span of 5 m. The slab is supported with hinge in the left support anda vertical cable located 1.5 m from the right support. The distance between thecables of the slab is 2.3 m. The slab is to carry a live load pressure of 2.4 kPa anda dead load pressure (including self-weight) of 4 kPa. Assume f’c = 27.6 MPa andfy = 276 MPa for main and temperature bars. Use 12 mm ∅ for main bars and 10mm ∅ for temperature bars. The slab is not exposed to earth or weather. Usethickness of slab of 120 mm. Use NSCP 2001.A W section steel purlin span 6.7 m between roof trusses on centers. The roof is assumed to support a dead load of 880 N/m2 of roof surface including self-weight and a live load of 816 N/m2 of horizontal roof surface projection. The slope of the roof truss is 1 vertical to 2 horizontal and the purlins are spaced 1 m on centers. Use A36 with Fy = 248 MPa. Assume all loads pass through the center of gravity of the section.
