Beam height (h)-600 mm
•
Effective depth (d) - 525 mm
⚫ Concrete compressive strength (f'c)=27 MPa
⚫ Steel yield strength (fy)=420 MPa
.
Steel reinforcement area (As) 1473 mm²
•
Modular ratio (n) = 8.2

stage when subjected to a bending moment of 81 kN m. Use the working stress method.
Solve the following problems: 1. Air pollution in Mexico City metropolitan area is among the worst in the world. The concentration of ozone in Mexico City has been measured at 441 ppb (0.441ppm). Mexico City sits at an altitude of 7400 feet, which means its atmospheric pressure is only 0.67 atm. (a) Calculate the partial pressure of ozone at 441 ppb if the atmospheric pressure is 0.67 atm. (b) How many ozone molecules are in 1.0 L of air in Mexico City? Assume T = 25 deg * C
