Reinforced Concrete
Strain measurements were being taken on two opposite faces of a column during a test.The column is pin supported at each end.At a particular load stage strains measured were,e1=0.002 and e2=0.0035, both being shortening.Compute the axial force,moment and curvature that is corresponding to this load stage.The material stress-strain relations are as given below.Neglect the second order effects.

1. The number of equilibrium equations available in 2D is 6. 2. The Method of Sections results in a 2D rigid body equilibrium problem. 3. Indeterminate trusses can only be solved by Method of Joints, not Sections. 4. By definition, truss members must be pin connected & carry only axial load. 5. Shear Force is the first derivative of Bending Moment. 6. Distributed Load is the integral of Shear Force. 7. The maximum Bending Moment is always at the center...

Question 2 I (a) Using a 459 strain gauge rosette placed on a mild steel structure, the following strains were established from the measurements taken:£x = 75x10", Eyy =-115x10-6 = 210 10-6 and Yxy yy (i) Determine the corresponding normal stresses Ox and and shear stress txy. For mild steel, use Young's modulus E= 205 GPa , Poisson's ratio v=0.3 and shear modulus G = 78.8 GPa. [6 marks] (ii) Using the values obtained in (i), determine the principal stresses...

Question 1 An end capped cylindrical pressure vessel with internal pressure p = fully supported at one end, is also subjected to a force F= 10 kN in the y direction at the other end as shown. The internal diameter of the pressure vessel is d= 160 mm and its thickness is t= 10 mm 3 MPa, assumed to be Determine the magnitudes of the stress components in x, y and z coordinates at points H and K and sketch...

The following figure 1(a) shows a part of a reinforced concrete building in a school. The structure consists of precast concrete hollow slabs that rests on the 10.8m long two reinforced concrete beams. The beams are supported on reinforced concrete columns. It is given that, on the top surface of the hollow slab, there will be a concrete screed with 50 mm thickness (assume density of concrete screed is 25 kN/m). In addition, there will be tiles that weigh 0.05...
