Explanation of Solution

Solid masonry:

It is termed as a masonry unit whose net cross-sectional area Anet in every plane, parallel to the ‘bearing surface’, is 75% or greater than the gross-sectional area Agross in the same plane.

Hollow masonry:

The net cross-sectional area Anet in each plane of masonry, parallel to the ‘bearing surface’, is less than 75% of the gross-sectional area Agross in the same plane. This is termed as hollow masonry.

Reinforced Concrete Design First Monthly Exam 24/02/2 Q1. A simply supported rectangular beam (300 x 400) mm and span (12) m with live load of from the soffit of the beam. Compute the stresses at mid-span of beam for the following (5 kN/m). At the centre of the beam the prestressing force of (120) kN is located at (50 mm) conditions: (a) Prestress + self- weight of beam (initial stage). (b) Prestress + self- weight of beam + Live Load (service stage). 3:00 400 120 K * 12m 5kN/m. 120 KN
A driven pipe pile in clay is shown in Figure (1). The pipe has outside diameter of 406 mm, and wall thickness is 6.35 mm. a. calculate the net point bearing capacity. b. calculate the skin resistance (1) by using a method, (2) by using A method. e. Estimate the net allowable pile capacity. Use FS-4. Figure (1) 5 m Saturated clay 30 kN/m² Groundwater table y= 18 kN/m 5 m Clay C-30 kN/m2 y= 18 kN/m 20 m C Clay -100 kN/m² 19.6 kN/m
A fully embeded precast, prestressed concrete pile is 12 m long and is driven into homogeneous layer of sand. The pile is square in cross section, with sides measuring 305 mm. The dry unit weight of sand is 16.8 kN/m, and the average effective soil friction angle is 35°. The allowable working load is 338 kN. If 240 kN is contributed by the frictional resistance and 98 kN is from the point load, determine the elastic settlement of the pile. Use Ep 21 x 10 kN/m², E, 30000 kN/m², and μ-0.3.
