2. Class members should each examine a different local project and determine the following: • Project cost per square foot • Economic Life • Design-construction time • Income in dollars per square foot • Compare the viability of different project types at different interest rates.

Question: Using the data obtained from the uniaxial compressive strength test given below:

a. Find the average uniaxial compressive strength (UCS) and standard deviation.

b. Make UCS classification (ISRM, 1978).

Question: A cylindrical rock sample with a diameter of 54 mm in the uniaxial compressive strength test

It was broken by applying a force of 160.2 kN. Since the angle between the applied load direction and the breaking surface is 30 °, the stresses acting on the breaking surface;

(a) Solve using the Mohr diagram (graphic method).

(b) Solve by analytical method.

Design a concrete mix for the superstructure of a building using DoE mix design method requiring a characteristic strength of 40MPa at 28days and a slump of 30-60mm. The materials available are ordinary Portland cement, and uncrushed fine and coarse aggregates of specific gravity of 2.65. The maximum nominal size of coarse aggregate is 10mm and fine aggregate confirms to the grading zone III. Neglect the effect of standard deviation and other factors.

1. What are the suitable type of Excavations required to remove the layer of fine grained soil with a high clay content soil directly beneath the topsoil? Moreover, it is observed from the building design that foundations shall be constructed nearby to each other. In line with the requirements, recommend the safe and sustainable type of excavation along with the construction plant team suitable to construction site situation?

2. What is the suitable type of Foundation to build a G+3 storey building transforms heavy loads to the ground and it is desired to have minimum settlement? The building will be built in a fine grained soil with a high clay content soil, and the construction site is a residential area which may contain obstructions, and consists of adjacent structures and the construction method of foundation shall not develop any ground heave.

According to the ground stability and site circumstances, propose the most desirable construction method of the foundation and construction plant.

3. What are the suitable type of Super Structure for constructing G+3 residential buildings?

Considering this, recommend the most desirable, safe and sustainable construction method for the super structure based on the most common form of construction in Al Mabelah area In Sultanate of Oman.

When do we use the Hook development length??? and is it applicable for the tension steel in both of +ve and -ve moments? or only negative??

pls explain it for me as much clear as possible

*write a typed answer pls

b) Give two construction applications/uses of cold-mix asphalt.

3- Name the material category (metallic, organic, inorganic) of asphalt and provide a justification for your classification.

critically discuss the chemical water quality parameters and why these are necessary

Q4: Experiments were conducted to determine the safe buckling load on columns with T-section
100 mm × 100 mm × 10 mm with different support conditions. When both ends of the columns
are fixed, safe crippling load carried by the column was found to be 60 × 103 N. Suggest the
length for other three columns for the same crippling load when the support conditions are
changed to one end fixed but the other end free, both the ends hinged and one end fixed but the
other end hinged. The cross section of the column is kept constant in all cases, and E = 200 GPa.
Take factor of safety = 4.
Instead of T section, a hollow column of same material having length 5 m and external diameter of
55 mm when subjected to a compressive load of 60 kN, there was a shortening in the length of the
column by 0.120 cm. Suggest a suitable value for the thickness of the column to withstand the safe
crippling load when one end of the column is fixed and other end is free?

Q1: Analysis of forces and moments were done for a simply supported beam having span 10 m
carrying a uniformly distributed load of ‘w’ kN/m over a length of 5 m from the left end support
and point loads ‘2w’ kN, ‘3w’ kN and ‘1.5w’ kN at distances of 6 m, 7 m and 8 m respectively from
the left end support. It was observed that the maximum bending moment acting on the beam is
equal to 192 kNm. Suggest a suitable value for ‘w’ based on this loading condition. How it will
change the reactions at the supports? What happens to the shear force and bending moment
values at the supports and at the points where loads acting? By plotting the bending moment and
shear force diagram for the beam, briefly conclude the relationship between the values for shear
force and bending moment.

Q5: Experiments were conducted to determine the deflection on a T- section steel girder 200 mm x 200 mm x 10 mm and a rectangular beam made up of concrete having breadth 15 cm and depth equal to 25 cm. T- section girder is used as a simply supported beam for a span of 4 meters but rectangular beam is used as a cantilever beam for span of 6 meters. Both beams are subjected to a uniformly distributed load ‘w’ N/mm run over the entire span. Suggest a suitable value for ‘w’ so that the maximum deflection in the simply supported beam does not exceed 17.65 mm. Compare the maximum value of slope and deflection for both steel and concrete beams. Modulus of Elasticity, E for steel = 2 x 107 N/cm2, E for concrete = 2.5 x 107 kg/cm2. What will be your suggestions to minimize the deflection on both steel and concrete beams based on the results obtained for the slope and the deflection of beams
