Center of Mass & Center of Rigidity | Reinforced Concrete Design

http://goo.gl/nmipcn for more FREE video tutorials covering Concrete Structural Design The objectives of this video are to briefly discuss about the center of mass and center of rigidity by understanding what their means as well as to talks about combination of center of mass and center of rigidity. The center of mass of a structure represents the point through which vertical forces act and the center of rigidity represents where lateral forces act through. First part of the video shows the formula of finding center of mass & demonstrates how to assess the constituents of the formula in greater details. Moving on, the video explains what resists lateral force in a structure; subsequently shows the total procedures of finding x and y variables whose are necessary to be known to get the acting point of the center of mass and rigidity. Later, the video talks eccentricity and how torsion takes places as a result of eccentricity in details. Finally, the video illustrates a graphical depiction of COM & COR.
