“…Compared to traditional construction, modular constructions have many connections as all of the individual modules should be connected to build the ultimate structure. Moreover, connections should be designed considering their deformation capacity, strength and stiffness [52]. However, cost and work schedule aspects should be taken into account in the design phase as the number of connections directly influences the budget and schedule of a project.…”

Modular Building Systems (MBS) offer numerous benefits in terms of productivity, sustainability and safety. Therefore, MBSs are considered as a viable option to sort out the housing crisis in Britain as well as to drive Britain towards sustainable construction. Development in materials, manufacturing techniques, connection types and structural designs with respect to offsite construction is essential to achieve sustainable goals. Recent advancements in steel manufacturing, including Cold-Formed Steel (CFS), have showed potential benefits in structural performance compared to concrete and timber. Meanwhile, research was conducted to enhance the structural capacities of CFS sections by introducing different cross-sections, composite sections and techniques including optimization. Built-up sections were developed by connecting more than one channel section, and various research studies were conducted to assess their structural performances. However, sustainable performance of built-up sections in modular constructions is still unknown. Hence, this paper intends to develop an MBS using built-up sections for better sustainable performance. Literature review was carried out on the sustainability benefits of MBSs in terms of economic, environmental and social aspects. In addition to that, numerical analysis was performed to investigate the flexural capacity of built-up sections with different screw arrangements to address the sustainable aspects of modular construction by introducing novel sections. The numerical description, results and validations are also stated. Numerical results revealed that flexural capacities of built-up sections are improved up to 156% than those of single sections. Finally, the utilization of built-up sections in modular construction with sustainability enhancement is addressed and illustrated in a conceptual diagram.

“…Berdasarkan hasil penelitian yang dilakukan oleh Adinda (2014) Pada saat perakitan di pabrik diupayakan semua sudah dalam sistem yang otomatis, sehingga dapat mencapai kualitas dan kecepatan yang efisien (Rajanayagam et al, 2021). Mempertahankan struktural yang tetap menjadi satu kesatuan pada saat pembebanan ekstrim dan beban yang tidak direncanakan meru-pakan perhatian utama saat merancang bangunan modular bertingkat.…”

Perkembangan penduduk harus diimbangi dengan pemenuhan kebutuhan rumah tinggal. Di Kota Besar masyarakat semakin sulit menjangkau harga rumah dengan luas yang sesuai dengan jumlah anggota keluarga. Proyek konstruksi yang sukses diukur dari 3 faktor, yaitu tepat biaya, tepat mutu, tepat waktu. Proyek seharusnya diselesaikan dengan biaya yang tidak lebih dari rencana anggaran biaya, pada saat serah terima harus diperiksa apakah proyek sudah sesuai dengan spesifikasi dan kualitas yang ditentukan, selain itu proyek juga harus diselesaikan tidak lebih dari waktu yang telah disepakati, dikarenakan ketiga tolak ukur tersebut, maka direkomendasikan pemenuhan kebutuhan rumah tinggal menggunakan sistem modular. Penelitian ini akan menjawab mengenai (1) Bagaimana kebutuhan rumah tinggal di Kota Besar dengan menentukan sampel di Kabupaten Tangerang? (2) Bagaimana efektifitas penggunaan sistem modular untuk rumah tinggal jika dilakukan proses pengkodean saat tahap konstruksi? Hasil penelitian menunjukan (1) Kebutuhan akan rumah tinggal untuk 2 orang dan 3 orang di wilayah Kabupaten Tangerang tergolong banyak, maka dari itu dibutuhkan proses pembangunan dengan biaya rendah dan efisien. Dengan melihat kondisi tersebut, sistem modular dirasa cocok untuk digunakan di Tangerang. (2) Pemberian kode pada sistem modular membuat lebih cepat dalam pemasangan dan dengan waste/sisa material lebih sedikit sehingga biaya lebih hemat. Selain itu, sistem modular untuk rumah tinggal sudah banyak dikembangkan di lapangan.

“…Chen et al [8] summarised the recent advancements of structural systems, design techniques and illustrated more than thirty IMCs, insisting also on the importance of manufacturing and constructional aspects such as ease of manufacturing, ease of installation, particularly the difficulties of fixing the fourth modular unit at the internal joint due to lack of access. Rajanayagam et al [42] and Nadeem et al [43] focused on some of the existing IMCs and emphasised the role of automated and semi-automated joints in solving constructional challenges in MBS. Most recently, Lacey et al [44] have focused on the experimental setups used to test the mechanical properties and failure modes of IMCs by classifying the test configurations into three main levels, analysing the efficiency of these setups for different types of frames (braced/unbraced), and providing insightful recommendations regarding the applicability of each type of experiment.…”
