| Summary: | The infrastructure development, especially the building construction,
increases every year as each life sector also develops in national and regional
level. Because of the importance of the building construction function in this case
the building construction of Sumbawa Regent Office as the community service
center and the control center of Sumbawa Regency government, it needs to have
evaluation on the construction reliability to maintain its structural performance
during the age plan.
The evaluation focused on the 3-floor main building and kept analyzing
the influence of wing deformation on the main building. The evaluation started by
collecting the secondary and primary data. The primary data was obtained by
testing on the structural elements of column, beam, and floor plate using the
method of non-destructive test to get the data on material quality, structural
component dimension, and condition of building damage. After that, there was the
calculation of loading that referred to the Imposition Planning Procedure for
House and Building (SNI 03-1727-1989) for static load and the Standard of
Earthquake Reliability Planning for Building Construction Structure (RSNI 03-
1726-201x) for dynamic load (earthquake load of response spectrum). The
evaluation on the ultimit limit performance of building structure was analyzed and
modeled using the SAP 2000 program. The modeling of building structure was
infill walls model. The strength of structural element was analyzed using the
Response 2000 program for elements of column and beam and the Shell 2000
program for element of floor plate.
The evaluation results are the natural vibration period of building structure
with Model Using Roof (MDA) is 0.291 second and frequency (f) 3.438 Hz while
Model Without Roof (MTA) is 0.308 second and frequency (f) 3.244 Hz. The
ultimit limit performance of building structure results in the value of deviation
between floors (story drift) at the safe limits, the level stability of building
(stabilty ratio) θ < 0.1, then there is no influence of P-Delta. The maximum
deflection as building separation between the main and wing buildings is about
0.90 cm on the Model MDA and 3.10 cm on the Model MTA, while existing
separation is 1.5 cm. Accordingly, that building was categorized unsafe against
impact when earthquake occurs on the Model MTA (RSNI 03-1726-201x). The
structure element strength of column, beam, and floor plate is in the safe condition
because the load working on the structure is not exceeded. |
