Abstract

Student Dormitory of Andalas University is one of the buildings for new students who come
from outside of Padang, Indonesia. In 2015, Andalas University received aid from the Public Works Ministry
of Indonesia to build the dorm. It was planned by a designed consultant using reinforced concrete (RC)
structure with a straight shape (I-shaped) RC shear wall. The review results of the design from the Technical
Engineer of Andalas University indicated that the designed building does not have enough carrying capacity
to resist the accumulation of all combined internal and external loads acting on the building structure.
Therefore, the strengthening of the building structure should be done. In the present study, the strengthening
method is proposed by modifying the I-shaped RC shear wall (I-shear wall) to be L-shaped RC shear wall (Lshear wall), which is installed at the building corners. The L-shear wall was installed on the building in two
ways, that is only on the 1st floor (2nd – 5th stories using I-shear wall) and on all building stories. The effect of
the L-shear wall in the building performance has been investigated based on parameters such as internal
forces of structural elements, story displacement, and story drift. The presence of L-shear wall only on the 1st
floor reduced the shear force and bending moment of columns and beams on the 1st floor and no much effect
on the other floors, while the addition of the L-shear wall on all stories decreased the internal forces on
columns and beams in all stories. The reduction of the inter-story drift of the building was more decreased by
the installment of the L-shear wall on all stories.
