1. Given the following information, determine the appropriate LRFD load combination and calculate the load acting on a typical roof joist (plf). The joists span 30 ft and are spaced 5 ft on center. Select the lightest K-series joist from the LRFD joist selection tables. Since this is for a roof joist, allowable deflection is L/240. In addition to the series designation, also indicate the capacity of the joists. Dead Load: 28 psf Roof Live Load: 20 psf Snow Load: 31 psf Rain Load: 23 psf Wind Load: 33 psf (Upward)

2. Roof joists are spaced at 2m and span 6m between supporting girders, and joist depth of 600mm. The allowable deflection limits for OWSJ are L/360 under snow load. The OWSJS are subjected to a dead load of 2.96kPa which includes the estimate joist weight of 0.15kPa, an occupancy load of 2.4kPa, and the following: SULS 1.99kPa SSLS = 1.25kPa Select a suitable OWSJ which satisfies the limit states design.

A floor system in a small building consists of wood plans supported by 50mm (nominal width) joists spaced at a distance of 0.40 m, measured center to center. The span length of each joist is 3.2 m. The uniform load carried is 5.8 kPa which includes the weight of the floor system. (Do not consider reduction of capacity of the beam) What is the cost of timber beams in a 2 meters span of floor (hint: determine how many beams in 2 meters span), , if the price of the timber is Php 65.00 / boardft.?
