8、: These alignment charts or nomographs are based on the following assumptions: 1 Behavior is purely elastic. 2 All members have constant cross section. 3 All joints are rigid. 4 For columns in frames with sidesway prevented, rotations at opposite ends of the restraining beams are equal in magnitude

9、and opposite in direction, producing single curvature bending. 5 For columns in frames with sidesway permitted, rotations at opposite ends of the restraining beams are equal in magnitude and direction, producing reverse curvature bending 6 The stiffness parameter L (P/EI )1/2 of all columns is equal

10、. 7 Joint restraint is distributed to the column above and below the joint in proportion to EI/L for the two columns. 8 All columns buckle simultaneously. 9 No significant axial compression force exists in the restraining beams. Adjustments are required when these assumptions are violated and the al
