For preparing a design calculation for the curtain wall system of the facade of a building, what is the sequence or step for whole design calculation? How many elements should be included to be calculated.

Calculate the field weights of the ingredients for 0.047 m³ of concrete by using ACI Method of Mix Design. Job specifications dictate the followings:

Cement content: 330 kg/m³

w/c: 0.58 (by weight, from the strength point of view)

w/c: 0.54 (by weight, from durability point of view)

Air Content: 1,40 %

For Fine Aggregate (Crushed): SSD Bulk Specific Gravity: 2.48, Total Moisture: 5,0 % and Absorption Aggregate: 2,8 %.

For Coarse Aggregate (Crushed): SSD Bulk Specific Gravity: 2.60, Absorption Capacity: 2.0 %, Total Moisture: 1.7 % and Dry Rodded Unit Weight: 1483 kg/m³.

Cement: Sulphate Resisting Cement, Specific Gravity: 3.18.

Describe in detail, the AISC Code in your own words.

A 400 mm concrete wall supports a dead load of 280 KN/m and a live load of 230 KN. The allowable bearing pressure is 230 KN/m2 and the level of the bottom of the footing is 1.5 m below the ground surface. Assume concrete weighs 24 KN/m3, that of soil is 15.74 KN/m3, fc’ = 20.7 Mpa, fy = 248 MPa,. Use 25 mm diameter reinforcing bars. Thickness of footing = 500 mm and concrete cover is 75 mm. Calculate the:

(a) effective soil pressure,

(b) width of wall footing, and

(c) spacing of bars at critical section.

2. A wall footing is to support a 400 mm wide reinforced concrete wall with a dead load of 270 KN/m and a live load of 210 KN/m. The bottom of the footing is 1.50 m below the final grade. Assume the soil weighs 15.78 KN/m3 and the allowable soil pressure is 190 Kpa. Use 75 mm as concrete cover, fc’ is 28 Mpa, fy is 415 Mpa, and concrete weights 23.5 KN/m3. Compute the:

1. Width and depth of footing
2. Spacing of 20 mm diameter main bars and 12 mm diameter longitudinal temperature and shrinkage steel
3. The development length required if bar location, coating, and size factors are all 1.0. Use normal weight concrete

Q1. Gombo Water and Sanitation Company Limited has been having a problem with regards to the operation of
the company which has caused the organization not to satisfy the needs of the customers due to frequent
breakdown of water and sewerage pumps, residents receiving brownish water and not addressing customer
complaints of high bills, residents not receiving adequate supply of water and leakages in the distribution.
The other problem has been frequent sewerage blockages which results in direct discharge of raw sewerage
into the Mulungushi River hence affecting the ecological process as the main sewerage pipe crosses the
river. In May this year, the company was given a fine by Environmental Management Agency of 50,000
Zambian Kwacha for discharging raw sewerage in the Mulungushi River due to non-function of the
Biological filters. You have been engaged as a consultant by the Government of the Republic of Zambia to
provide solutions to the challenges the utility is facing. What professional advice would you give?

You work for a surveying company. Main roads WA has contracted your company to set out the centre line of a new highway to be constructed. You have found the following video online about a robot that can do the work more effectively:[10 marks]
