Paper ID: 243 from the UGM Faculty of Engineering successfully won the title as the best paper and best speaker at the International Conference on Sustainable Civil Engineering Structures and Construction Materials (SCESCM), which took place in Malaysia. The International Conference on Sustainable Civil Engineering Structures and Construction Materials is an international conference that is held once in two years.
This year, it was the University Teknologi Mara, Malaysia's turn to organize the 5th SCESCM. It raised the theme entitled, "Transforming The World, Foster The Sustainable Development Goals". By now, SCESCM is a forum for discussion between researchers, practitioners, and academics in civil engineering to further support sustainable development goals.
"There were 280 speakers from various universities and countries over the world attended at SCESCM 2020," said Ali Awaludin, S.T., M.Eng., Ph.D., at the UGM Faculty of Engineering on Tuesday (19/1).
He explained that there were two selection stages at SCESCM 2020, namely a paper submission and a conference. The paper submission stage was held until 31 July 2020, and papers reviewed then proposed to attend the conference held on 8-9 December 2020.
"SCESCM 2020 awarded us for two categories, namely best paper and best speaker, and we won both of them," he explained.
Paper ID Team: 243 Faculty of Engineering UGM consists of Andika Monanta Emilidardi, Angga Fajar Setyawan, S.T., M.Eng., Ph.D., Ali Awaludin, S.T., M.Eng., Ph.D., Prof. Ir. Iman Satyarno, M.E., Ph.D., and Mukhlis Sunarso, S.T., M.T. Paper ID: 243 presented the design of multi-directional earthquake dampers.
The earthquake dampening tool is known as the Finned Tubular Shear Panel Damper (FTSPD). FTSPD has a concept that uses a ductile material that can manage its post-yield stiffness during the plastic phase.
"The goal is that the FTSPD can be steady in anticipating earthquake energy so that the structure of the building under its protection will be safe. After going through selection stages, the UGM team eventually won the best paper award at the 5th SCESCM 2020," he conveyed.
Andika Monanta Emilidardi added that the FTSPD tool's design aimed to lessen and anticipate earthquakes in many ways. Consequently, there would be a reduction in the structure's force and moment reactions due to the earthquake. He added that the earthquake damper tool indeed dissipated the earthquake energy that hits the structure.
"The principle of the Hysteresis FTSPD earthquake damper is to take advantage of the material plastic properties. Hence, steel material with good ductility is utilized to manage device stability in anticipating earthquake energy so that the tool can absorb large earthquake energy. "The researchers selected geometric with the tube shape to accommodate earthquake shots from various directions," he said.
Andika also explained that this FTSPD design idea was a component that absorbed the largest energy in a building. It uses a low structural component as the trick to looking for the most vulnerable structural component.
Accordingly, FTSPD was designed to have a larger energy dissipation capacity than other structural components. By this design, it is expected that FTSPD can absorb most of the earthquake energy so that there would only be insignificant damage from the building structure due to the earthquake.
Andika also admitted that currently, there had been no direct benefits from this tool design because no one had implemented this tool directly in buildings. The design of this tool is still in process. Only the test results showing FTSPD met expectations as an earthquake damper because it matched the existing standard criteria.
"Hopefully, in the future, the implementation of FTSPD can minimize the destruction and risk of earthquakes to buildings," he explained.
In order to make this FTSPD tool later, it will cost 1 million rupiahs to apply this in every area. An equitably affordable price is one of the benefits of this tool.
"It's only approximately 1 million rupiahs. It is very affordable compared to the lead rubber bearing earthquake damper in which the cost reaches up to tens to hundreds of millions. Regrettably, the tool is still in the process of the experimental trial stage," Andika added.
