- W2187285804 abstract "Most parts of Indonesia are quite exposed to the risk of majorearthquakes, but many traditional timber houses were survived due toearthquake. One of Indonesian traditional timber house is Omo Hada, anindigenous house of Nias people was survived with no damage after the Mw 8.6Northern Sumatra Earthquake. In Japan, many residential building has been builtby using wood material in order to prevent collapse during major earthquake.Wood is considered as one of the most important and reliable constructionmaterials, 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 softwareand Extended Distinct Element Method (EDEM) as the basis theory. Wallstat is acollapse analysis program which already used in many previous researches tosimulate collapse during times of seismic motion. In this study, there are tenmodels that were analyzed due to El Centro Earthquake 1940, Kobe Earthquake1995 and Modified El Centro Earthquake 1940, those are, Model 0, 1, 2, 3, 4, 5up 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 secondstory. Model 6, 7, 8, and 9 are the models reinforced with bracing at the firststory columns. Whereas in Model 10 is Model 5 which are subjected to modifiedEl Centro Earthquake 1940.The models reinforced with vertical shear walls at second story collapsed andit 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 higherthan the original model, that is, Model 0. Otherwise, Model 6 through 9 survivedand the base shear force are smaller than that of Model 0. This bracingreinforcement system showed the effectiveness in preventing earthquake andbase 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 thatthe still survive due to local scale earthquake. Moreover, internal force values inall models are higher than the original model. From all those aforementionedparameters, it can be concluded that bracing reinforcement at first story is moreeffective in preventing structure from collapsing due to earthquake than themodels with additional vertical shear walls at second story.Keywords: Ammu Hawu traditional house, Borassus flabellifer, Wallstatsoftware, Extended Distinct Element Method (EDEM), Vertical shear wall,Brace, Collapse mechanism." @default.
