Question:

Imagine the fire department had to evacuate the 25th floor of an office building. For firefighters to safely reach people at this height, how long would the truck’s ladder have to be and how much would it weigh? Based on this, do you think Pierce should manufacturer this apparatus? Explain.

Q1) Design a concrete mixture proportions which will be used for offshore concrete platform. Norway is a world leader on offshore concrete platforms with 1a of the world’s 30 larger offshore concrete structures located on the Norwegian continental shelf. The first of these platforms where the Ekofisk Tank installed in 1974 and the last was Troll gravity based structure installed in 1996. The Sakhalin project is located in a harsh and artic environment where concrete structures have proven excellent characteristics with a minimum of maintenance. 80 mm slump value is required for the Sakhalin project. 28-days concrete characteristic strength is 2b MPa. It is required that no more than 1 test result in 100 will fall below the specified strength. The fine aggregate has a fineness modulus of 2.60 and Zone 3. For Coarse Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.65, Absorption Capacity: 2.b %, Total Moisture: 1.c % and Dry Rodded Unit Weight: 1345 kg/m3. For Fine Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.70, Total Moisture: 3.d % and Free Moisture: 2 %. Cement: Portland Composite Cement, Specific Gravity: 2.97. For 0.e5 m3 of concrete, binder amount is calculated as 120 kg (Use ACI Method of Mix Design)

Q2) What would be the maximum aggregate size used for the given mixture properties by using ACI Method of Mix Design. 28-day specified concrete strength is 3b Mpa, standard deviation is choosen as 3.a Mpa and it is required that no more than 1 test result in 200 will fall below the specified strength.
Project Title: Detoration of wood column of a commercial building
Project summary: Wood deterioration at the lower level of a heavy timber column, which supports five floor levels, was remedied by removing a section of column and the construction of a new concrete pier and footing.
For Coarse Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.60, Absorption Capacity: 1.8 %, Total Moisture: 2.3 % and Dry Rodded Unit Weight: 1430 kg/m3.
For Fine Aggregate (Crushed): SSD Bulk Specific Gravity: 2.70, Total Moisture: 3.c % and Free Moisture: 1.d %. FM= 2.65, Zone II.
Cement: Portland Composite Cement, Specific Gravity: 3.01. For 0.2a m3 cement is calculated as 12b kg.

Q3) use the data in question 2 and determine the amount of chemical admixture required for 0.b% and 0.cd%

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.
