Q.2 The required design span for the beam given in Q.1 is increased to 18 ft. The design loads
are the same as given in Q.1 Check the adequacy of a 10"x16" 10 Caribbean Pitch Pine –
(Select Structural) for this these design conditions.
The timber floor framing for a building comprise floor joists using 2" wide nominal lumber
is to be constructed as shown in Fig. 1. The Dead load (D) = 26 lbs./ft² (inclusive of joists
and flooring) and the live load L= 40 lbs./ft². Lateral torsional buckling is prevented for all
members and normal service conditions and temperatures are expected.
(i) Design the floor joists using 2" wide nominal lumber using Southern Pine No. 1
(ii) Design the floor beams using Caribbean Pitch Pine (Select Structural). (Assume a 8" x
14” trial section to estimate beam self-weight for your initial design). Density of
Caribbean Pitch Pine = 50 lbs/ft³ (800 kN/m³).
P12.38 WP At a point on the free surface of a stressed body, a normal stress of 64 MPa (C) and an unknown positive shear stress exist on a horizontal plane. One principal stress at the point is 8 MPa (C). The absolute maximum shear stress at the point has a
magnitude of 95 MPa. Determine the unknown stresses on the horizontal and vertical planes and the unknown principal stress at the point.
