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.

WebJun 27, 2024 · The unfactored girder reactions for lane load and truck load are obtained from the superstructure analysis/design software. These reactions do not include dynamic load allowance and are given on a per lane basis (i.e., distribution factor = 1.0). WebY-Y and X-X Axis Forces allow you to apply service (unfactored) shears and moments to the footing. Dead, live, and short-term components are allowed, and the values can be either negative or positive. ... Factor of safety against overturning by applying the loads and moments about each axis. Biaxial analysis has no effect on this number. 999 ... WebOct 23, 2024 · The list given the individual un-factored load case to be considered, but there are many combinations that are possible, depending on your situations. For example, for gravity LC G = (a)+ (b), or (c); for wind, LC W = LC G + (d); for seismic with/without wind LC = LC W + (e), and LC G + (e). tellinga
