Abstract
This article informs about temporary housing necessity for the Earthquake victim's refugees in Indonesia. After the disaster, management of mitigation is needed, especially to cover the primary necessities of housing. There is another temporary housing proposed by previous research, such as RISHA and RUSPIN, that are formed from precast concrete material. Huntara 1.0 by November 10 Institute of Technology are also proposed after Lombok Earthquake and were formed from timber. In this article, an alternative design of temporary housing using a combination of Steel and Cold-Formed Steel is proposed. The loading estimation used in proposed modeling assumes that the buildings are located in Yogyakarta as one of the cities that has the highest value of PGA. Another assumption of loading is based on the available Indonesia Building Code, include the calculation of structural ability and design. The roofing system is an essential component of this housing using a trusses system with a lip C75.35 profile, using available research trusses configuration. The central column of the moment-resisting structure system is using Double lip C100.50 profile and beam using trusses Lip C80.35 profile. Overall, a new alternative design of 36 m2 temporary housing is presented in this article with a relatively economical budget. The prototype and experimental loading test have to be done first before this design can be safely used extensively.
Highlights
Every country that is located in an earthquake-prone area must have its mitigation action to withstand the natural disaster
In August 2018, Lombok was struck by 7 SR earthquakes that made more than 76.765 houses collapsed, and 555 fatalities counted (CNN, 2018)
All the results presented here have been through a proper structural analysis process
Summary
Every country that is located in an earthquake-prone area must have its mitigation action to withstand the natural disaster. AISI has its standard for earthquake resistant building design so that CFS can be widely developed (American Iron and Steel Institute, 2013) Compared to their hot-rolled counterparts, CFS members are often more economical and efficient due to their lightweight, ease, and speed of construction and greater flexibility in manufacturing (Mojtabaei, Kabir, Hajirasouliha, & Kargar, 2018). These are the main reason cold-formed can be used for the solution of temporary housing needs of the post-earthquake area. Another design alternative of Low-cost Earthquake resistant house using CFS has been done, in that research [51,84] m2 house was designed with 36 million rupiahs in cost (Hardwani & Patil, 2013)
