Abstract

The seismic weight according to code will be used for seismic calculation and defined by mass source. The application in ETABS has a 3-ways to define seismic mass: 1. From self and specified mass, 2. From loads. 3. From self and specified mass and loads. If the mass source is not defined properly, seismic forces will not be calculated correctly and so the base shear value will also be incorrect. The purpose of this article is to obtain the mass source from 3-ways in ETABS which is near to the manually calculated Mass and its effects. The case study is a 17 multi-story building, and from the results of the analysis and discussion it is concluded that: the lowest time period, equivalent lateral force, story shear, story drift are the 'From self and specified mass', followed by the 'From load with DL+0.5 LL'. Next is the 'Self and specified mass and load with DL+0.5 LL', and the last is 'Self and specified mass and load with DL+ LL'. The value of 'From load with DL+0.5 LL' is near to the manually calculated Mass with 'DL+LL', and thus corresponds to the recommendation by ASCE 7–10.
