Abstract

An earthquake of magnitude 7.6 on Richter scale struck the offshore of West Sumatera in 2009. It took place
approximately 50 km to the Northwest from Padang. The similar earthquake may very likely strike
Padangsidimpuan as the principle of building construction in Padangsidimpuan uses the strong column weak
beam as shown by the results of the visual field survey. Meanwhile, the principle in designing seismic-resistant
building is the strong column weak beam. One of the reasons why a building fails in an earthquake is the
selection of soft story structure. The research objective was to determine increase stiffness, maximum load
capacity due to the brick as a load, the structure, structure the column confinement and structure based on SNI
to a shop buildings in the city Padangsidimpuan who reviewed the feasibility resistant to earthquakes. The
method applied is the numeric simulation with finite element method. The result shows that the maximum base
shear force of bricks in x axis is 1,268.12 kg (loading brick) 2,121.03 kg (brick as structure), 2,339.96 kg
(confinement of brick column), and 2,924.36 kg (SNI standard brick). The result also shows that the maximum
shear force base of bricks in x axis is 1,265.70 kg (loading brick) 6,048.19 kg (brick as structure), 6,395.49 kg
(confinement of brick column), and 6,702.15 kg (SNI standard brick). The base shear force increases 1.75 times
(brick as structure), 1.85 times (confinement of brick column), and 2.31 times (SNI standard brick) compared to
the loading brick. The stiffness increases 4.52 times (brick as structure), 5.08 times (confinement of brick
column), and 5.54 times (SNI standard brick).
