Stiffness of a moment frame
http://www.ce.memphis.edu/6136/PDF_notes/h_slabs.pdf Webbecause of its greater stiffness, the beam will tend to take a larger share of the column-strip moment than the adjacent slab. For an interior panel surrounded by similar panels supporting the same distributed loads, the stiffness of the supporting beams, relative to slab stiffness is the controlling factor.
Stiffness of a moment frame
Did you know?
Moment-resisting frame is a rectilinear assemblage of beams and columns, with the beams rigidly connected to the columns. Resistance to lateral forces is provided primarily by rigid frame action – that is, by the development of bending moment and shear force in the frame members and joints. By virtue of the rigid beam–column connections, a moment frame cannot displace laterally without bending the bea… WebExplain how moment frames work to stabilize buildings Predict whether or not a building will resist lateral loads based on its lateral resisting system Background Wind and earthquakes create lateral loads on buildings that need to be resisted. Two ways in which these loads can be resisted is through the use of shear walls and moment frames.
