When using elastic analysis, member stiffness should be reduced to account f6r the degree of cracking the onset of significant yielding in the structure. Scott Victor Shneur ,Hru-old 0.

These motions ~nee horizontal and vertibal ground accelerations at the earth's surface, which in it is to use earthquake ::1: ground motions ~ in past earthquakes to simulate the ~havior of structures, the required analysis prOcedwes are complex, and the ~~:tlysis resulls are sensitive to the characteristics of the individual groi. A wide-flange section satisfies these requirements if its flange and weh width-to-thickness ratios are less than or equal to the corresponding limits listed in Table l ·A, which is summarized from the requirements in Table D 1.

The following consensus standards are printed in Part 9 of this Manual: The American Institute of Steel Construction , founded in 1921, is the nonprofit technical specifying and trade organization for the fabi:icated structural steel industry in the United States. Structures· Similar to Buildingse I 2. Lateral loads can then be iterated by ramping them so rhat the analysis captures the additional changes to the system stiffness during each step. Careful attention to all aspects of the design is necessary in the design of composite systems, particularly with respect to the general building layout and detailing of members and connections. .

Additionally, it is necessary to account for material overstrength that may alter relative strength and stiffness. The Institute bears no responsibility for such material other than to refer to it and incorporate it by reference at the time of the initial publication of chis edition.
