Calculate the weight of the wall from the given Cross Section by considering the unit weight ofreinforced and plain concrete as γc=2Y kN/m3.
Design a square base plate to support 10 mm thick pipe column with an inside diameter of 300 mm. The base plate minimum dimension is 500 mm. To design plate thickness, convert the circular perimeter of the pipe into an equivalent square with an area equal to the original circle. The loads are PDL = 850 kN and PLL =420 kN. Assume that the pipe is to rest on a very wide slab. Use A-50 steel and concrete fc’ = 35MPa and LRFD.

STRUCTURAL ANALYSIS II The given plan below shows a 2-way floor system carried by 1-story 2-bays frame system as shown in sec 1-1. The floor is 18 cm in thickness and made with reinforced concrete with fc'= 28MPA and fy= 420MPA, yc= 24kN/m3. The floor is to carry a service live load of 5 kN/m2. Assume that E is constant for all structural elements in the system. Determine the following: 1- Extract he structural system of beam ADG, beam BEH, frame ABC, and frame DEF, showing the loads to be carried on each element from the slab, and include the own weight of the element given that beams ADG and BEH have a section of 180mm in depth and 400 mm in width. Where the girder of all frames has a cross section of 300 mm in depth and 800mm in width. 2- Analyze beam ADG using slope- deflection equations method. 3- Analyze beam BEH using moment distribution method. 4- Analyze frame ABC using moment distribution method.
