Calculate the governing load combination for a secondary beam with effective width = 2.0 m Dead load Weight of slab = 3.0 kPa Ceiling services = 1.0 kPa Self-weight of beam = 1.0kN/m Imposed load - 0.2 kPa

What is the main value in pre-stressing pre-cast concrete columns?

List three common categories of stress that must be known before a beam size can be determined.

What are the two major methods of determining lateral loads?

A continuous foundation is required in a soil where c=10kN/m2, =26, and =19.0kN/m3. The depth of the footing will be 1.0 m. The dead load and the live load are 600 kN/m and 400 kN/m, respectively. Determine the required width for the foundation based on allowable stress design with FS = 3, using Eq. (6.10) and Table 6.1.

How is concrete consolidated?

State whether the following are true or false. a. Load carrying capacities of timber piles are less than those of steel or concrete piles. b. If the load carried by the pile cross section decreases linearly with depth, the frictional resistance per unit remains the same at all depths. c. The point load is mobilized well before the shaft load. d. Soil-pile friction angle can be greater than the friction angle of the soil . e. Bored piles are high displacement piles.

For the mat in Problem 16.15, what will be the depth, Df, of the mat for FS = 3 against bearing capacity failure? 16.15 Consider a mat foundation with dimensions of 18 m 12 m. The combined dead and live load on the mat is 44.5 MN. The mat is to be placed on a clay with cu = 40.7 kN/m2 and = 17.6 kN/m3. Find the depth, Df, of the mat for a fully compensated foundation.

Redo Problem 6.2 using the general bearing capacity equation [Eq. (6.28)]. A 5.0 ft wide square footing is placed at 3.0 ft depth within the ground where c = 200 lb/ft2, = 25, and = 115.0 lb/ft3. Determine the ultimate bearing capacity of the footing using Terzaghis bearing capacity equation and the bearing capacity factors from Table 6.1. What is the maximum column load that can be allowed with a factor of safety of 3.0?

Use the composite beam tables and select a W-shape and stud anchors for the following conditions: Span length = 18 6 Beam spacing = 9 ft Total slab thickness = 51 2 in. (the slab and deck combination weighs 57 psf). Lightweight concrete with a unit weight of 115 pcf is used Construction load = 20 psf Partition load = 20 psf Live load = 225 psf Fy=50 ksi and fc=4 ksi A cross section of the formed steel deck is shown in Figure P9.8-9. The maximum live-load deflection cannot exceed L/360 (use a lower-bound moment of inertia). a. Use LRFD. b. User ASD.
