1. Creep is one of deformation that occurred in concrete structure. Give one example that can be associated with creep problem in concrete structure. Define what is creep and discuss on how the creep occurred in choosen example.

2. Moisture movement in concrete is one of the factor that influencing shrinkage and creep. Elaborate this effect and how to differentiate between these properties.

3. With coastal and offshore concrete structures directly exposed to seawater, why does most of the deterioration occur in the tidal zone? From the surface to the interior of concrete, what is the typical pattern of chemical attack in sea structures? Discuss the mechanism for the chemical attack in the structures.

4. Concrete has been used since ages. In your opinon, how is relavant the advanced knowledge in concreting for the construction industries.

A train with six 80 K cars accelerates from a station at 4 ft/sec².

a What torsion “T” is exerted on the support structure? What torsion is applied if another train coming into the station on the opposite track decelerates at the same rate?

b A 40’ wide, 5’ deep beam with top 30’ above street level supports the tracks beyond stations. To clear traffic and to light the street, it is a hammerhead supported by a 6’ diameter, 20’ tall solid reinforced concrete column (“J”). For the trains accelerating in opposite directions, find t _max and angle of twist qat z = 0 ground level, using height L= 20’. The “J” of the hammerhead, beam and taper is ginormous.

A simply supported beam of span "L" and uniform flexural rigidity EI, carries a point load (P=wL) at mid-span and a uniformly distributed load (w) throughout the span. The maximum deflection is -------.

Critically evaluate the engineering, procurement and construction (EPC) contract and the engineering, procurement and construction management (EPCM) contract as used in the civil engineering industry. Critically evaluate how each contracting strategy is used in the real world

Consider a sharp crested (uncontracted horizontal) rectangular weir 1.0 m long and 0.8 m high. The channel receives a flow of 0.3 m3 /sec. What will be the depth and velocity in the channel?

1. Recall a work task, hobby, or other activity that you perform regularly.

2. name the activity and list sequentially the actions you do to complete the activity

3. Describe the main differences between doing your activity as you perform it regularly and any variations to those steps you would make to improve your activity.

4. Reflect on the complexity of your list and the number of steps needed to complete the activity:

• Did variation affect your activity?
• If so, did the variation cause your activity to be easier or more difficult?

Discuss the process of determining static earthquake and wind forces in high rise buildings using any code/guidelines.BS or Eurocode for example.

Outline the considerations/effects of structural systems, structural shapes, grounds conditions, building height, etc.

What are the main processes and processes alternatives comprising sludge treatment? Show your answer in a generalized sludge –processing flow diagram

Your task is to build a wastewater treatment plant to handle all of the domestic wastewater produced by a housing estate. Using population equivalent, PE = 65000, design, describe and calculate briefly the sizes of all the unit processes in the treatment plant that are going to be built.

Explain Briefly Components of Strain Energy.

The wastewater treatment plant will also treat wastewater originating from the industrial activity of pulp and paper in the near future. Proposed and describe appropriate unit processes that can be added to the plant.

Geotechnical Engineering

-Draw in scale the distribution of the passive pressure

- Calculate the total forces and its components (in case there is)

-Locate the force in m with respect to the lower point
