Kajian ini membentangkan kelakuan struktur sistem kerangka keluli terbentuk sejuk untuk perumahan mampu milik. Objektifnya adalah untuk mengkaji tingkah laku sistem kerangka struktur keluli terbentuk sejuk dan keluli siap panas yang menggabungkan dinding beban, papak beban ringan dan untuk membandingkan berat bahan yang digunakan pada struktur keluli terbentuk sejuk dan keluli siap panas bagi perumahan mampu milik. Empat jenis model yang terdiri daripada 243 bahagian digunakan untuk menganalisis sistem rangka struktur keluli. Model 1 adalah sistem kerangka struktur keluli terbentuk sejuk dan Model 2 adalah sistem kerangka struktur keluli siap panas. Kedua-dua struktur keluli menggunakan panel dinding ringan dan papak komposit ringan. Model 3 dan Model 4 juga sistem kerangka struktur keluli terbentuk sejuk dan sistem kerangka struktur keluli siap panas. Kedua-dua struktur ini menggunakan bahan yang berbeza dari dinding dan papak yang merupakan dinding bata dan pratuang konkrit bertetulang. Semua model disediakan dalam AutoCAD dan dianalisis menggunakan perisian STAAD.Pro. Kajian ini mendapati bahawa bahagian nipis keluli boleh meningkatkan nilai pesongan. Peningkatan panjang bahagian dan nisbah kelangsingan akan mengurangkan rintangan tujahan. Apabila beban yang digunakan meningkat, ubah bentuk lengkokan juga meningkat. Selain itu, penurunan rintangan ricih disebabkan oleh penurunan kawasan ricih. Bahagian tebal dan bahan ringan yang digunakan dapat mengurangkan nilai putaran kilasan. Selain itu, perbandingan berat struktur keluli menunjukkan bahawa struktur keluli terbentuk sejuk dengan panel dinding ringan dan papak komposit ringan adalah model terbaik kerana berat ringan dan lebih banyak manfaat untuk perumahan yang mampu dimiliki _________________________________________________________________________ This study presents the structural behaviour of cold-formed steel framing system for affordable housing. The objectives are carried out to study the behaviour of cold-formed steel structural framing system incorporating lightweight load bearing wall and slab and to compare the weight of the material used on the cold-formed steel structural of affordable housing. Four types of model that consist 243 members are used to analyse the steel structural framing system. Model 1 is cold-formed steel structural framing system and Model 2 is hot-finished steel structural framing system. Both of steel structures utilizing lightweight wall panel and lightweight composite slab. Model 3 and Model 4 are also cold-formed steel structural framing system and hot-finished steel structural framing system. Both of this structures using the different materials of walls and slab which are brick wall and precast reinforced concrete. All of the models are drawn in AutoCAD and analysed using STAAD.Pro software. This study found that the thinner of steel section can increase the value of deflection. The increasing of the member length and ratio of slenderness will decrease the buckling resistance. When the applied load increases, the buckling deformation is also increase. Besides that, the decreasing of the shear resistance is caused by the decreasing of the shear area. The thicker section and the lightweight material used can decrease the torsional rotation value. Other than that, the weight comparison of the steel structure shows that cold-formed steel structure with lightweight wall panel and lightweight composite slab is the best model due to light weight and more benefits for affordable housing.
