31、(1 I I I EFFECTIVE LENGTH FACTOR, K 1; The Effective Length of a column, KL, has been used in the equations for allowable compression stress in the column. K is the ratio of the effective length of an ideal- ized pin-end column to the actual length of a column with various other end conditions. KL r

32、epresents the length be- tween inflection points of a buckled column. Restraint against rotation and translation of column ends influences the position of the inflection points in a column. Theoret- ical values of K for some idealized column end conditions dom comply fully with idealized restraint a

33、gainst rotation and translation, the recommended values suggested by the Column Research Council are higher than the idealized values. Columns in continuous frames unbraced by adequate attachment to shear wails, diagonal bracing, or adjacent structures depend on the bending stiffness of the rigidly

34、connected beams for lateral stability. The effective length factor, K, is dependent on the amount of bending stiffness supplied by the beams at the column ends. If the amount of stiffness supplied by the beams is small, the value of K are given in Table C-l. Since column end conditions sel- could ex

APPENDIX D COMPUTATION OF PLASTIC SECTION MODULUS Z* The plastic modulus Z is the statical first moment of one half-area of the cross section about an axis through the centroid of the other half area. When a section is built up

44、from plates or shapes of more than one yield point, the plastic moment should be computed on the basis of equilibrium on the cross section with all fibers stressed to the appropriate yield point in either tension or compression. A 2- a AI (shaded) = A2 (clear) = A/2 a = distance between centroid of

45、A, and A2 2 = aA, = aA2 *Information in this Appendix is obtained from the Commentary of AIS1 Bulletin 15. Values of Z for rolled sections are listed in the Mun- uul of Steel Construction, Eighth Edition, 1980, American Institute of Steel Construction. 700 APPENDIX E Selected Conversion Factors Usef
