Buckling capacity of cold-formed steel structure column member with perforation section in affordable house framing system

Buckling capacity of cold-formed steel structure column member with perforation section in affordable house framing system / Zafira Nur Ezzati Mustafa
Tetiang C terbentuk sejuk biasa digunakan dalam pembinaan dinding pasang siap. Disebabkan isu tentang kos keseluruhan keluli menjadi pertimbangan utama dalam rancangan membina rumah mampu milik untuk mangsa banjir, sector pembinaan memperkenalkan konsep bukaan pada bahagian web. Oleh itu, dalam kajian ini, kajian berangka menumpukan pada kapasiti kekuatan lengkokan dengan pembukaan pada web tetiang telah dijalankan. Ujikaji dimulakan dengan menentukan jarak antara tetiang yang sesuai untuk kerangka rumah. Analisis kerangka dilakukan menggunakan STAAD Pro. menggunakan tetiang C tanpa tembukaan. Pembukaan berbentuk bulat digunaankan dalam ujikaji ini dengan saiz 0.4D, 0.6D, dan 0.8D (D=180mm). Jarak diantara pembukaan adalah 150mm, 250mm dan 350mm. Untuk specimen bukaan 0.4D dan jarak antara hujung tetiang dan pembukaan bulat adalah 539mm mempunyai capacity lengukkan yang paling tinggi (26.59 kN). Pengurangan kapasiti lengkokan adalah 5.31% daripada kapasiti lenggkokan tetiang C tanpa pembukaan dan pengurangan isipadu adalah sebanyak -2.16%. untuk kes yang sama tetapi saiz bukaan 0.8D, ia mengurangkan kapasiti lengkokan sebanyak 22.52% dan isipadu -6.85%. Kesimpulannya, kajian ini telah meninjukkan tetiang C yang tidak mempunyai bukaan mempunyai keupayaan lengkokan yang lebih tinggi. _______________________________________________________________________________________________________ Cold formed C-column have been used in interior wall construction. Because of the issue of material cost become one of the factors need to be considered in affordable house construction, the construction sector has introduced the concept of opening to the column web. Besides, this study focus on the buckling capacity for C-column cold formed steel with perforation. This study starts with determining the suitable spacing for the space column for the affordable house. Analysis house frame has been done in STAAD Pro. analysis using C-column without perforation. Opening with circular shape has been used in this study with the size of 0.4D, 0.6D and 0.8D (D=180mm). Spacing within the opening is 150mm, 250mm and 350mm. for the specimen with 0.4D opening and the edge distance is 539mm have the highest buckling capacity (26.59 kN). Reduction of buckling capacity is 5.31% from C-column without perforation and reduction of volume is -2.16%. for the same case with 0.8D opening, the buckling capacity reduce with 22.52% and volume is -6.85%. the conclusion of this study, C-column without perforation have higher buckling capacity compare to C-column with perforations.
