| Summary: | The construction of high-rise buildings is indeed a challenge for building designers,
especially in earthquake-prone zone such as Indonesia. Planning of buildings in
earthquake-prone zone is quite difficult. Especially in high-rise buildings that tend
to have high flexibility, so that the detailing of earthquake-resistant buildings for
high-rise buildings can be more complex. Although there have been many types of
buildings with various forms of high-rise buildings that have been built, the
behavior of each building can be different, depending on the shape of the floor plan,
type of building, and the height of the building. In the context of the civil
engineering workspace, especially the planning aspect, it is also necessary to pay
attention to the loads working on the building structure. If the loads on the structure
exceed the capacity of the structure, the structure can be damaged and even
collapse. Failure of structural elements can potentially result in progressive
collapse.
Progressive collapse is a collapse caused by the failure of elements in a small part
of the building but can result in total collapse. Because progressive collapse
becomes very dangerous, it is necessary to anticipate that even if there is damage
to some elements of the building, the building will not experience a total collapse.
This is the basis of this study to determine the form of progressive collapse. The
main purpose of this study is to determine the potential for progressive collapse in
high-rise buildings. The plan refers to the WTC because the framed-tube system is
still relatively rare for buildings in Indonesia. With this type of building, it can be
known that the damage to the exterior elements will affect the interior elements,
and so is the opposite.
The model will be designed using ETABS software, then the structural response will
be checked which refers to SNI 1726:2019. After all the seismic design criteria
checking fulfill the requirements, a progressive collapse analysis will be checked.
For this progressive collapse analysis, there will be two scenarios. The first
scenario, several columns will be omitted because they are considered as fail
elements. The second scenario, the object will be subjected to a large transverse
load on several columns. Then, the analysis to be checked is a linear static analysis,
which calculate the value of bending moment ratio, demand capacity ratio and
robustness indicator which refers to GSA 2003 regarding progressive failure. At the end of the study, it is known what conditions cause the potential for progressive
failure, with the failure pattern starting with beam elements. |
