RCC Structures Design If p₁ and p₂ are mutually perpendicular principal stresses acting on a soil mass, the normal stress on any plane inclined at angle θ° to the principal plane carrying the principal stress p₁, is: [(p₁ - p₂)/2] + [(p₁ + p₂)/2] sin 2θ [(p₁ - p₂)/2] + [(p₁ + p₂)/2] cos 2θ [(p₁ + p₂)/2] + [(p₁ - p₂)/2] sin 2θ [(p₁ + p₂)/2] + [(p₁ - p₂)/2] cos 2θ [(p₁ - p₂)/2] + [(p₁ + p₂)/2] sin 2θ [(p₁ - p₂)/2] + [(p₁ + p₂)/2] cos 2θ [(p₁ + p₂)/2] + [(p₁ - p₂)/2] sin 2θ [(p₁ + p₂)/2] + [(p₁ - p₂)/2] cos 2θ ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 700/3C m = 1400/3C m = 3500/3C m = 2800/3C m = 700/3C m = 1400/3C m = 3500/3C m = 2800/3C ANSWER DOWNLOAD EXAMIANS APP

RCC Structures Design In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 25 mm 10 mm 15 mm 20 mm 25 mm 10 mm 15 mm 20 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If T and R are the tread and rise of a stair which carries a load w per square metre on slope, the corresponding load per square metre of the horizontal area, is w (R + T)/T w (R/T) w √(R² + T²)/T w √(R + T)/T w (R + T)/T w (R/T) w √(R² + T²)/T w √(R + T)/T ANSWER DOWNLOAD EXAMIANS APP
