AHM MED SHAWKY Y’s EXAM ON N 05‐02‐2014 1‐ As per the truss figu ure shown, kn nowing that E=250Gpa& A==380mm2. Caalculate the displacement at the joint EE.
The displacement at any point = F*L/EA The displacement at B = (25*1000*4000)/ (250*1000*380)=1.05mm The displacement at E = 2*1.05=2.10mm
2‐ In the ssame truss ab bove. Calculatte the displaccement at thee joint B. 3‐ As per the beam figu ure shown be elow, knowingg that EI is coonstant. Calcu ulate the defleection at C.
Deflection at C= 5w*L4/384EI= (5*12*244)/(384*EI)=51840/EI
4‐ As per the beam figu ure shown be elow, knowingg that EI is coonstant. Calcu ulate the defleection at C.
It's the longest path of activities in the project
5‐ Definitiion of critical path method d? 6‐ Estimatte time in PER RT are calculaated Normal o or Binomial oor Logarithmicc or integratio on? 7‐ Change e order in anyy project will iimpact what??
The time and the cost
Normal
12-18% 8‐ Moisture content in timber used in construction?
106.22-6.22=100.00'
9‐ ASHGAL means: Ministry of Public work Or Ministry of urban planning or Ministry of water and Other because it's Puplic Work Authority not Ministry electricity or other? 10‐ If a level instrument elevation is 106.22’, what’s the ground level if the reading on the staff 6.22’? 11‐ If you have a shallow foundation carrying light structure with drainage embedded in the soil and found that the soil under the foundation is expansive. What’s the proper soil replacement for that: well graded sand well compacted or well compacted sand with 30% fines or concrete replacement or same expansive soil but well compacted? Well graded sand well compacted 12‐ One of the road traffic measurements are found as 250‐350‐200‐320‐288‐266 at 15 minutes period. Calculate the PHF? 13‐ Hardness of water is defined as: The total solid content in the water or the total dissolved content in the water or the resistance to increase the PH value or the resistance to soap scrum? 14‐ The nominal moment at any concrete rectangular section are calculated as: Mn=Asfs(d‐a) or Mn=0.85fc’ba(d‐a/2) or Mn=Asfs(d‐a/2) + 0.85fc’ ba? Mn=0.85fc'ba(d-a/2) 15‐ The first step to define the project scope is to: analyze the budget or analyze the work strategy or define the major activities according to client’s requirement or meet the team members?
To define the major activities according to client's requirement 16‐ The first step to identify the road geometry in road design is to: know the functional classification or know the traffic flow or know existing design or know roads network? 17‐ Usage of plywood in formwork preferred because: the tensile strength is equal at any direction or the tensile strength is maximum at short direction or the tensile strength is minimum at long direction The tensile strength is equal at any direction or the tensile strength is minimum at short direction? 18‐ If the investment of a project with 2,000,000QAR start with 150,000QAR with annual profit 10%. Calculate the return period in years? (Note: Formulas are given in the exam) 19‐ The preferred location for a new library will be on: Beside airport area or beside central area with parking facilities or remote area or high population area? Central area with parking facilities 20‐ Working break structure (WBS) is defined as: 1)Graphical presentation 2)Top‐Down structure with program adopted 3)Down‐Top structure with program adopted 4)useful in complex projects. Is the correct answer: 1,2 OR 1,3 OR 2,4 OR 3,4? 2,4 21‐ The air entrapment in concrete will: 1)increase the workability 2)improve the durability 3)reduce he concrete density 4)increase concrete strength. 1,3 22‐ The bearing capacity for the soil will be affected by which: shear strength parameters or foundation dimensions or foundation depth or others?
shear strength parameters
0.2 23‐ Poisson’s ratio in common concrete is: 0.2 or 0.3 or 0.45 or 0.25?
3 layers
24‐ How many layers of concrete is required in slump test: 4 layers or 2 layers or 3 layers or 7 layers? 25‐ What’s the mean of crashing in the project?
To increase project resources in order to reduce the project total duration
