Determine the allowable load on a 3 m long layered built-up column made up of 6 nominal 2”x 6” pieces of Apitong lumber (actual size 1.5” x 5.5”). The column does not have full lateral bracing to prevent weak axis buckling of individual laminations. However, the specified fastening requirements for nailed built-up columns are satisfied. Assume column pinned in one end and fixed to other end. Consider normal duration of loading. The column used is visually graded sawn lumber.

A timber wall 50 mm wide x 50 mm deep and having a height of 3.50 m is assumed to be hinged at top and bottom. It is subjected to an axial load of 15228 N on the centroid. A uniformly distributed load is also acting along the weaker axis of its entire height. The wall is made up of Apitong wood and stresses are shown in the table (Use 80% stress grade). To be safe, the actual stress should not exceed allowable stress, Given: bending and tension parallel to grain = 16.5 Mpa modulus of elasticity = 7310 Mpa compression parallel to grain = 9.56Mpa compression perpendicular to grain = 2.20 Mpa shear parallel to grain = 1.73 Mpa Determine the following: a. the allowable compressive stress b. the allowable bending stress c. the allowable uniform load "W" it could carry

The terrazzo floor finish imposes a uniformly distributed load of 20 psf, while the live load over the entire slabbed area, can be taken as 50 psf. The unit weight of concrete is 150 pcf and the self-weight of the steel beams can be ignored. a) Show the tributary areas over all the beams on a plan drawing. b) Calculate the total factored loads on the beam shown on gridline '2' and draw its loading diagram, showing the total factored loads as well as its factored reactions. to .0-,9 .0-8 0-,21 ,0-,
