000019823 520__ $$2eng$$aMexico City’s code for the design and construction of masonry structures was recently revised to include new and updated provisions related to a wide range of subjects, including an important thrust towards the formal determination of the material properties. The committee decided to drop the Simplified Method for analysis of masonry buildings as it was observed that the method was also used for structures which did not satisfy the prescribed requirements related to the applicability of the method. The lateral drift limits for different types of masonry structures were updated based on recent shaking table test results. A new minimum depth for grade beams which support structural walls has been prescribed. This is an important issue considering that many walls are supported on beams at base of a building to leave space for vehicle circulation and parking. A new procedure for estimating the shear strength of masonry walls has been prescribed. The procedure takes into account the aspect ratio of the walls and the interaction of the wall shear capacity with the overturning moment on top of the wall. Also, the provision for the shear strength contribution of the horizontal reinforcement was updated. In confined masonry walls embedded tie-columns require considerably wider masonry units thus the minimum required wall thickness was also increased. A new recommendation has been included related to the modelling using the Finite Element Method and the provision related to the modelling using the Wide Column Model has been updated.
