QUESTION 1 An individual Simply Supported timber beam, 350mm (deep) x 175mm (wide) x 2000mm (long) is used to support only Point Loads at mid-span, consisting of Unfactored Permanent Point Load G 3 kN and Unfactored Variable Point Load, Qk = 19 kN. Ignore self-weight of the timber beam. The Load Duration Class is of "Permanent" category and a Service Class of 3 is anticipated. a) For this beam, a factor ksys to be adopted shall be 1.0. Explain why this factor of 1.0 should be taken and not 1.1. b) Evaluate the Design Actions (1.35GK + 1.5Qx) c) Evaluate the Bending Moment d) Evaluate the Shear Force e) Verify the joist safety for bending moment based on Eurocode 5 f) Verify the joist safety for shear force based on Eurocode 5 g) Verify the joist safety for deflection (1.0Gx + 1.0Qk) based on Eurocode 5

Q-A timber beam, 100 mm wide and 150 mm deep, supports a UDL over a span of 2 m. If the safe stresses are not to exceed 28 MPa in bending and 2 MPa in shear, find the maximum load that the beam can support.
A square tied column is 430 mm x 430 mm with 8- 28 mm Grade 415 bars. The lateral ties are 10 mm diameter bars with 40 mm concrete cover. If the unsupported length is 2.50 m and Ku = 1.0, what is the safe ultimate load on the column based on the 2001 NSCP? f'c = 28 MPa. Moment on the column is neglected.
Floor beams of Group B timber are spaced 1.2 m centres, on a clear span of 3 m, with a bearing of 20 cm at each end. The dead load of roof covering is 2000 N/m' and live load is 1500 N/m?. Design the beam for inside location. The timber is of standard grade. Take E = 11000 N/mm?.

Determine the maximum floor load that the simply supported interior stringer can carry based on the capacity of the section shown. Use fc' = 30 MPa and GRADE 275 rebars. The slab thickness is 100mm, stringers are placed 3.1 meters on centers, has a span length of 7.5m, a web width of 300mm, effective depth of 480mm, effective concrete covering of 100mm and the interior stringers have 6-25mm rebars. Unit weight of concrete is 24kN/cu.m. USE NSCP 2010 the answer is kN/m WALL LOAD FLOOR LOAD 1.
I am trying to figure out which equations were used to solve this problem.
The steel fabricator your company partners with has steel rebar available in Gr. 60 steel for Numbers 3, 6, and 8. If the beam you are designing is meant to support a distributed live load of 1.0 k/ft and a distributed dead load of 0.5 k/ft, which bar size (and how many) should you use? Additionally, what are the spacing requirements for No. 3 stirrups in this beam? There is a required cover of 1" and fo' = 5000 psi. 10" 18'
