Unfactored overturning moment

WebJun 20, 2024 · I have few queries regarding calculating overturning moment and resisting moment. 1) Will the overturning moment be base shear x Total tower height or summation of (story shear of individual story x Elevation of each story from base). 2) How the resisting moment will be calculated? Create an account or sign in to comment WebFeb 29, 2016 · You can use nodal forces to calculate overturning moment. You'd multiply each nodal force by its elevation above the base of the structure. There's nothing special about ELF method and using it to calculate OTM per the building code. The code described process just a simplification/abstraction of basic statics. – William S. Godfrey- S.E.

WebOverturning is checked at the base of the footing at the extreme edge of the toe. Each portion of soil weight, concrete weight, surcharge loading, lateral soil pressure and lateral water pressure is taken into account. Each piece is either part of the resisting moment or the overturning moment. Figure 2: Overturning Diagram WebTension forces result from the overturning action (i.e., overturning moment) caused by the lateral shear load on the shear wall. In some cases, the chord may be required to be a thicker member to allow for an adequate hold-down connection or to withstand the tension and compression forces presumed by the beam analogy.
