| dc.description.abstract | The development of higher education in Semarang City has made
Muhammadiyah Semarang University (UNIMUS) strive to continue to
improve the quality and quantity of facilities and infrastructure to support
lecture activities. The construction project of the University Hospital of
Muhammadiyah Semarang is located on Jalan Kedungmundu Raya 18,
Kedungmundu, Tembalang, Semarang City. Building A has shearwall on
the emergency stairs and elevator and has large columns of 70 x 90 cm and
70 x 70 cm so that the building is too rigid and inefficient.
The structural redesign of Building A of the University Hospital of
Muhammadiyah Semarang which consists of 10 floors with an open frame
structure. The main focus of this planning is to reduce column dimensions
so that they are more efficient and less rigid but still within safe limits
according to applicable requirements. The method used in this research is
to model the upper and lower structures of Building A of UNIMUS Hospital
using a conventional plate structure model. Calculation of loading analysis
using SAP2000 application.
The results of the changes in the dimensions of the columns that are
minimized affect the stability coefficient of the structure. Structural
responses in the form of base shear, lateral displacement, and story drift,
from the results of re-planning and existing show safe limits. Some bore pile
dimensions have not changed but the reinforcement used is heavier than the
existing and some have changed, the size is smaller, and the reinforcement
used is heavier than the existing. The existing RAB amounted to
Rp18,841,631,615 while the re-planning RAB amounted to
Rp17,306,609,399, the difference was Rp.1,535,022,215 and obtained an
efficiency of 8.4170%. | en_US |
