Abstract
Planning of building structures, especially high-rise buildings, requires a structural analysis to obtain the most effective and efficient dimensions and configurations of structures that lead to planning that is resistant to earthquake shocks and lateral forces. The column structure of the building which has a vital role in the structure. Columns must be able to withstand the working forces so that no structural failure occurs. In this research, the building that will be analyzed is the auditorium building as well as a 3-storey lecture building located in the city of Pekanbaru. In this structure on the ground floor of the building there are no sloof beams so it is very worried about its strength or stiffness against horizontal forces and earthquake forces. The analysis of the strukctur was carried out using the finite elemnt method. The finite element method is a method that is widely used in analyzing the calculation of hingrise building structure. It is hoped that with the help of this finite element method, analysis of the structure of the auditorium building as well as a 3-story earthquake-resistant lecture building can be simpler and more stable in resisting the working forces. The results showed 80X80〖 cm〗^2 basement can withstand the load that work stably. If the structure uses uniform coloumns from the top floor to the basement floor, it can be use 50X50〖 cm〗^2 coloumns because rhe coloumns are able to withstand soil and earthquake load. The deviation beetwen floors that occurs is still included in the category where the deviation that occurs is smaller than allowable deviation for both floors 1 and 2 as well as in the X and Y. The p-dela effect on the structure is also still included in the category where the stability coefficient (θ) is smaller than maximum coefficient (θmax) then the coloumn structure is able to withstand the effect of p-delta. The coefficient of stability (θ) for the first floor is 0,01 and second floor is 0,001 and the maximum stability coefficient (θmax) for the first and second floors are 0,091.
