Resumen:

The code for eolic design in Mexico City, Mexico, [1], establish for the case of prismatic buildings, a lateral displacement of the interstory height divided over 300 as the service allowable threshold but, for comfort conditions, it says that the accelerations due to dynamic load should be less than 0.04g. For the calculation of such accelerations no methodology is provided for longitudinal or transverse direction. Because of that, buildings in Mexico City are not revised to cover this requirement. In this work, accelerations that are longitudinal and transverse to the wind direction are calculated for prismatic buildings with different geometric ratios by using recommendations proposed in the Japan [2], US [3] and Canada [4] codes and considering the design velocities in Mexico City and hurricane zones in Mexico. Results indicate that the acceleration threshold as proposed in the Mexican code NTC [1] is exceeded for the case of the transverse accelerations, in buildings with certain natural periods and for some eolic zones in Mexico.
