Unformatted text preview: MANHATTAN COLLEGE CIVIL & ENVIRONMENTAL ENGINEERING DEPARTMENT ==================================================================== FALL 2009 DR MOUJALLI HOURANI ======================= CIVL 3020102 STRUCTURAL ANALYSIS I ============== ================================== Moment Area Method Theorem 1 For two points A an B on a continuous elastic curve (there are no hinges between A and B), the rate of change of slope of the elastic curve between points A and B is equal to the area of the M/EI diagram between A and B. θ B – θ A = area under the moment diagram of the curve M/EI between A and B Theorem 2 For two points A an B on a continuous elastic curve (there are no hinges between A and B), the tangential deviation at a point B from the tangent line drawn to the elastic curve at A is equal to the moment about B of the area of the M/EI diagram between A and B. Sign Convention: 1 Change in slope is positive if the area of the M/EI diagram is positive....
