| description | Most parts of Indonesia are quite exposed to the risk of major
earthquakes, but many traditional timber houses were survived due to
earthquake. One of Indonesian traditional timber house is Omo Hada, an
indigenous house of Nias people was survived with no damage after the Mw 8.6
Northern Sumatra Earthquake. In Japan, many residential building has been built
by using wood material in order to prevent collapse during major earthquake.
Wood is considered as one of the most important and reliable construction
materials, since it is a renewable and has low weight due to its properties.
Collapse mechanism of Ammu Hawu Traditional House with Palm wood
(Borassus flabellifer) as main material was analyzed by using Wallstat software
and Extended Distinct Element Method (EDEM) as the basis theory. Wallstat is a
collapse analysis program which already used in many previous researches to
simulate collapse during times of seismic motion. In this study, there are ten
models that were analyzed due to El Centro Earthquake 1940, Kobe Earthquake
1995 and Modified El Centro Earthquake 1940, those are, Model 0, 1, 2, 3, 4, 5
up to 11. Model 0 is original model with no reinforcement. In the Model 1, 2, 3,
4, and 5 are the models reinforced with additional vertical shear wall at second
story. Model 6, 7, 8, and 9 are the models reinforced with bracing at the first
story columns. Whereas in Model 10 is Model 5 which are subjected to modified
El Centro Earthquake 1940.
The models reinforced with vertical shear walls at second story collapsed and
it was found that soft-story occurred due to the El Centro and Kobe Earthquake.
It was also found that base shear force values in Model 3 through 5 are higher
than the original model, that is, Model 0. Otherwise, Model 6 through 9 survived
and the base shear force are smaller than that of Model 0. This bracing
reinforcement system showed the effectiveness in preventing earthquake and
base shear force to whole structure. Soft-story did not occur in these models.
Model 10 also survived due to modified El Centro earthquake. It indicates that
the still survive due to local scale earthquake. Moreover, internal force values in
all models are higher than the original model. From all those aforementioned
parameters, it can be concluded that bracing reinforcement at first story is more
effective in preventing structure from collapsing due to earthquake than the
models with additional vertical shear walls at second story.
