3.3.4 Mass

California Administrative Code 2019 > 6 Seismic Evaluation Procedures for Hospital Buildings > 3 Procedures for Building Systems > 3.3 Configuration > 3.3.4 Mass
JUMP TO FULL CODE CHAPTER
There are no significant mass irregularities; there is no change of effective mass of more than 50 percent from one story to the next, excluding light roofs.
For buildings designed and constructed in accordance with the 1989 or later editions of Part 2, Title 24, the evaluator may consider this condition as mitigated, and no calculations are necessary. The deficiency is in the distribution of mass in the building. The effective mass is the real mass consisting of the dead weight of the floor plus the actual weights of partitions and equipment. Where mass irregularities exist, a dynamic analysis shall be performed to compute the vertical distribution of seismic forces.
