If water is seeping, the effective stress at any point in a soil mass will be different from the static case. It will decrease or increase depending on the direction of seepage. With help of sketches, describe what will happen to effective stress if the water is seeping downward through a soil layer.

In a two – story building, an exterior column is to be designed for a service dead load of 1000 KN, maximum live load of 1500 KN, dead load moment of 60 KN m, and live load moment of 90 KN m. If the column dimensions will be restricted to 400 mm x 500 mm, fc’ = 27.6 MPa, and fy = 414 MPa, calculate the required column reinforcement.

Topic - Construction: Structural, loads, tension
1.) Explain why pure tension members are the most efficient structural types for carrying building loads?
2.) How structural members behave when they are subjected to tension, compression, torsion, and bending forces in structures.

A zenith angle was measured six times with both faces of a total
station. The average direct
reading is 86°34′31″ with a standard deviation of ±12.8″. With the
reverse face, it was
observed as 273°25′12″ with a standard deviation of ±8.8″. What is
the most probable value
for the zenith angle in the direct face?

Superstructure Frames: Construction
Using all the different "design types" of superstructure frames (Concrete frame, Timber Frame, Steel Frame), how would you "design/build" a high-rise in your area (California, Fresno), and what types of structural systems would you use? You may make geographical assumptions to fit your model building.

A retaining wall with sloping back, of vertical height 9m retains soil of density 1.6 Mg/m3, and angle of friction 30o. The soil slopes upwards at 20o to the horizontal from the back edge of the wall, the angle between the slope and the back of the wall is 100o. Cohesion 10kN/m2, angle of friction between soil and wall is 25o but there is no cohesion between them. Find the thrust on the back wall per metre run using trial values of 25, 30, 40, and 45o for the inclination for the plane of rupture to the vertical.
