A STUDY OF REINFORCED CONCRETE COLUMN STRUCTURE TO
COMPARE OF STEEL COLUMN STRUCTURE
(CASE STUDY ON INDONESIA EDUCATION MUSEUM BUILDING
YOGYAKARTA STATE UNIVERSITY)
Indonesia education museum building which consists of two floors has a
unique architectural style and in the earthquake zone 3, its design is using a system of
intermediate moment frame bearers (SRPMM) to carry the gravity and seismic loads.
The frame of the building is quite unique, so the author is interested in reviewing of
the structure. In this study is limited on reviewing the structures of the frame and the
aims of the study: (1) Expenses of gravity and seismic loads, (2) Analyzing the
strength and ductility of columns, and (3) Comparison the use of reinforced concrete
columns and steel columns.
The design of the frame was using the 3D and analysis assuming the
dimensions of each frame in according to the real building ground. The author used
Etabs version 7.10 for earthquake load analysis based on SNI 03-1726-2002 the code
of earthquake resistant building standards of assigning, analysis of concrete structures
based on SNI 03-2847-2002 about regulation procedures for reinforced concrete
structures, and SNI 03-1729-2002 about steel structure design procedures for
structural design of steel columns.
Based on engineering drawing, obtained K1 column uses 400 mm x 400 mm
using 8D16 for the longitudinal reinforcement, shear reinforcement P10-100 on the
pedestal and P10-150 on the middle of the space area. K2 column uses 400 mm x 400
mm using 6D16 for the longitudinal reinforcement, shear reinforcement P10-100 on
the pedestal and P10-150 on the middle of the space area. From the results shows of
data analysis to K1 column uses 400 mm x 400 mm using 8D16 for the longitudinal
reinforcement, shear reinforcement P10-120 on the pedestal and P10-200 on the
middle of the space area. K2 column uses 400 mm x 400 mm using 6D16 for the
longitudinal reinforcement and shear reinforcement P10-120 on the pedestal and P10-
200 on the middle of the space area. For the design of steel columns was taken from
the Mnb as Mr for column interaction diagram (MN) on its balance point. It was
obtained I-profile steel 350mm x 350mm x 10mm x 16mm for the whole portal
columns. Employment cost of reinforced concrete column total is Rp. 56,038,214.36
while total cost of the work of steel columns is Rp. 130,938,080.00.
