Abstract : INT-DDAM is a program for the dynamic design/analysis of structures composed of beams and/or springs. It can accommodate up to 120 static degrees of freedom and up to 48 dynamic degrees of freedom. Input consists of joint coordinates, material properties, member cross sectional properties, joint connection data, mass data and base accelerations. Output consists of all input, the overall structural stiffness matrix, the dynamic flexibility matrix, natural frequencies, mode shapes, modal weights, inertial forces, modal joint displacements and member forces, deflections and stresses.
