A timber wall 75 mm wide, 75 mm deep and 3.50 m high is assumed to be fixed at the top and bottom. It is subjected to uniformly distributed load of 388 N/m acting along the weaker axis of its entire height. The wall is made up of Apitong wood with 80% stress grade with properties as shown: Bending and tension parallel to the grain = 16.5 MPa Modulus of Elasticity in Bending = 7310 MPa Compression parallel to the grain = 9.56 MPa Compression perpendicular to the grain = 2.20 MPa Compute for the following: a) Allowable compressive stress b) Allowable bending stress c) Maximum axial load %3D %3D %3D
6. Timber floor: The cross-section of the beam is 8x22cm (bxh), axial spacings 0,60 m. Timber class C24. Span of beam measured between walls is 5,20 m. Self weight of floor is 1,50 kN/m. Imposed load of floor is 2,00 kN/m2. Design required reinforcement. Only consider ULS. Please make appropriate drawing.
1. A rectangular beam section is 10 in. wide and has a structural depth of 13.5 in. Reinforcement consists of two No. 8 bars. Given that the strength normal weight concrete is 4000 psi and there is NO shear reinforcement in the section, determine the nominal shear capacity allowed by the ACI Code. (5 pt) (Hint: No web reinforcement, so Vc = 8λ¸^(pw)¹/³√fcbwd shall be used).
Given a rectangular section of b = 300mm, h = 400mm, a, = a', = 40mm; the concrete is of grade C30, the steel is HRB400. Find the reinforcement (A, and A') required for a load of M = 218kNm and an axial compression N= 396KN. %3D
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?.
A laminated wood beam consists of eight 2.25 in. × 5.00-in. planks glued together to form a section b = 5.00 in. wide by d = 18 in. deep, as shown and w = 663.2 lb/ft. If the allowable strength of the glue in shear is 105 psi, Determine:(b) the shear stress in the glue joint at H, which is located 4.5 in. above the bottom of the beam and at a distance of x = 86 in. from the left support. Assume that the beam is subjected to the load w determined in part (a). [Answer: τH = 19.34 psi]
