“…Masonry panel used in this proposed model is defined as an equivalent diagonal strut. For linear analysis in previous research found (Amalia & Iranata, 2018) that as substitution of masonry panel Holmes equation (Holmes, 1961) is the closest to the experimental test of Mehrabi (Mehrabi, Shing, Schuller, & Noland, 1996). Equivalent diagonal strut defines in the structural analysis must have the same thickness and elastic modulus with the masonry panel.…”

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 m 2 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.

“…The fact that bare frames are less rigid and less resistant than fully or partially infilled walls. From this observation, it is evident that it is advantageous to take these walls into account in the modeling process [3,9,11,12].…”

The influence of chained masonry walls, which represents a special case of masonry infill without gap, on the seismic response of reinforced concrete buildings is extremely important due to their wide use in this type of building. We can consider the period of building as the key parameter to study this influence. In this article, we had carried out a comparative study of several 2D models of a multi-storey reinforced concrete building with a brick chained masonry wall using the response spectrum method in the ETABS finite element software, following the prescriptions of the current Algerian seismic code. This study included the use of the number of spans, the span length, the number of storeys, the thickness of the chained masonry wall, the ground soft storey, the openings in the walls, and the short column for studying the influence of these to the walls. The values from the numerical simulation were compared with those from the formula of the period of building, provided by both the Algerian and European codes. Based on the results obtained, we were able to assess the influence of chained masonry walls on the seismic response on this type of buildings. Through this article, we have concluded that these walls have a great influence on the overall behavior of reinforced concrete buildings under seismic loading. HIGHLIGHTS Clarify the importance of numerical simulation of chained masonry walls in the design of reinforced concrete buildings Give recommendations to the current Algerian seismic code for properly design the infilled buildings with chained masonry Know the great danger marked in the current conceptions, which neglect these walls in the phase of conception Give to the infilled reinforced concrete buildings an adequate design in case of earthquake loadings GRAPHICAL ABSTRACT

“…Institut Teknologi Kalimantan Integrated Laboratory Building is going to build using reinforced concrete structure. Reinforced concrete structure is one kind of structural type using combination of concrete and rebar material with the intention of bearing loads and forces (axial, shear and moment) of the building other building elements such as brick walls as a component to divide each space in the building according to their respective functions (Amalia, 2015) (Amalia et al 2017). The planning of the building structure of the lab has not yet taken into account the infilled brick walls as one of the structural elements and is only considered as an architectural component.…”

Generally, brick wall (hebel) is considered as non-structural element, which never be counted to bear structural load. But, if carefully calculated, brick walls take part in structure load bearing. In the purpose of reducing the main structural element properties, the brick wall needs to be considered in bearing structural load. In this article, the brick walls modelled as compressive bracings. Using the structure analysis program, the model showed some significant differences in terms of internal force. From the analysis, the differences of moment, shear, axial and torsional force between open frame model (usual model, OF) and compressive bracing (CB) model were 38.17 kN.m; 58.03 kN; 181.75 kN dan 44.18 kN.m, respectively, where the first model had the bigger numbers than the latter model. Displacement of OF model was quite larger than CB model, with the value of difference was up to 85.35% for the X direction structures, and 70.83% for the Y direction. Final properties used for the design are smaller compared than original design, 30/60 to 40/60 for the beams, 50/50 for the columns with the different reinforcements 16-D22 for the second model compared to 20-D22 for the first one. The depth of slab on the second model was 180 mm, slightly smaller than the first model, 190 mm. It can be concluded that using compressive bracing model, structural properties of ITK Integrated Laboratory Building may greatly be reduced, compared to OF model.
