Pengaruh Pasangan Dinding Bata Pada Respon Dinamik Struktur Gedung Akibat Beban Gempa

For analysis purpose, the model system of structure is created as open frame structure rather than massive structure. However, the brick wall will affect to the behavior of the dynamic response when the earthquake induces the structure. The results of structural analysis by time history method using El-Centro earthquake, it reveales a significant difference of base shear between two types of structural model: (i) brick wall structure and (ii) non-brick wall structure. The base shear exists on the brick wall structure 20 percent greater than non-brick wall structure. Therefore, a structure without brick wall will be more irressistant due to the earthquake. The structural analysis using static equivalent method as point out in Standard of Earthquake Resistant for Building and Non Building (SNI 03-1726-2012) revealed that earthquake distribution loads relatively equal for brick wall structure and non-brick wall structure. The difference of earthquake load approximately 10 percent among two type of structure. Thus, it could be concluded that static equivalent method is more reliable to estimate the earthquake load of the structure rather than other method. This research suggests that in the structural design practicality, the effect of brick wall should be considered as a part of the structural analysis model.
