ABSTRACT: The Main Lecture
Building of Engineering Faculty of Diponegoro University construction process
start form June 2010 and be expected to finish at November 2010 but until
October 2015 this building can not used as it planned because the construction
process have some trouble. Design of this building still use the old guidence
that is Earthquake SNI 03-1726-2002. This day that guidence has been updated
become Earthquake SNI 03-1726-2012. Because of that this building need to
studied so the building can accord with the new guidence. The purpose of this
study is to design the structure strengthening so the building can accord with
the new guidence. The method of this study is collect the data of laboratory
examination. This data will use to determine the quality of materials for
calculate nominal capacity. Then redesign the structure using SAP 2000 so that
we can know the forces in every element of this structure. Then compere these
forces with nominal capacity of the existed structure which is manually
calculate under guidence of Concrete SNI 03-1726-2013. If the forces from SAP
2000 analysis bigger than the nominal capacity then the element need
strengthening. The reviewed element are beam, column, joint and caisson
foundation with strengthening use fiber reinforced polymer under guidence of
ACI 440 and concrete jacketing. The result of analysis based on Earthquake SNI
03-1726-2012 show that some element in this building can not hold the forces.
Beam can not hold the shear forces. Because of that, beam need the FRP shear strengthening
to increase the nominal capacity. Beside beam, column also can hold the forces
there are axial and moment. Because of this column need to use the concrete
jacketing method to increase the nominal capacity. Concrete jacketing method
more efficient than FRP strengthening for column.
