Experimental Analysis of Cold-Formed Steel C-Sections with the Notch Subjected to Axial Compression
Mohd Syahrul Hisyam Mohd Sani,Fadhluhartini Muftah,Cher Siang Tan 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.4
Studies on the use of cold-formed steel (CFS) C-section, which is a civil engineering material, in building and civil engineering work are still on-going. The advantages of the CFS C-section are becoming so interesting that it is often being used as a roof truss system, storage rack, and wall framing. In order to have a roof truss system with a strong, safe, and stable condition, a study on truss member was carried out using the cut-curving process. Before the CFS C-section was curved, the process started by cutting the section in a proper way. A parametric study was conducted to determine the suitability of the cut pattern which recognised as a notch in the section and find out whether or not the notch depth would affect the ultimate load of the CFS C-section column. The study of CFS C-section was separated into two parts; firstly, to investigate the mechanical behaviour of the column in different notch depths and secondly, to investigate the behaviour in different column height with fixed notch depth. The notch width of 3 mm and notch spacing of 100 mm for both parts were fixed. Total specimen for both parts were 15 specimens. The results of the study showed that the reduction of the ultimate load was about 56 – 65% of the variation of notch depth section when compared with the normal section. Therefore, the ultimate load of the section with the notch decreased when the notch depth increased. In addition, the study illustrated that the reduction of the ultimate load was 64 – 82% of the variation of column height between 100 mm to 500 mm. Finally, the average percentage of the column height was 72% which can use in the modification of CFS C-section without notch to CFS C-section with notch calculation.

Bending Behaviour of Different Types of Timber I-Joist
Wan Mohd Nazri Wan Abdul Rahman,Nor Yuziah Mohd Yunus,Mohd Omar Mohd Khaidzir,Mohd Syahrul Hisyam Mohd Sani 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.5
Engineered wood I-joist is a structural system that comprises of flanges and web elements, and utilised as beams in buildings. Both elements must work together as a structural system to fit and meet the strength behaviour of a solid wood beam. The main objective of the study was to determine the bending strength behaviour of I-joist which produced from three types of jointed technique (finger, L-butt and nail plate) of oriented strand board (OSB) web element with two types of flange element (Keruing solid wood and laminated veneer lumber (LVL)). A total of 18 specimens of I-joist were tested to determine the bending behaviour, especially the modulus of elasticity (E) and modulus of rupture (MR). From the result of testing, LVL flanges specimen were obtained almost as strong as the specimens with solid wood flanges. Additionally, either solid wood or LVL flange was shown non-significant variances in bending strength behaviour because the MR values of the I-joist were insignificantly affected by flange element material. The I-joist specimen with finger jointed web was observed to be the strongest specimen when compared with other joints. Furthermore, the weakest joint among the three types of joints were fabricated with nail plate jointed web. The failures mode of the I-joist specimens were observed to fail due to tension or compression.

Cold-formed steel (CFS) is a popular structural and non-structural material that is utilised as roof truss, wall panel and storage racks. But nowadays, CFS is selected and proposed as column and beam in building construction. CFS with open-section and very thin thickness is prone to deform and buckle in large condition. Therefore, the problem must be solved by proposing a new section that is matched up or formed of two or more open-sections to be one new section, shape and cross-section area. There are two types of channel-section and a connection is used to produce a bolted built-up CFS beam in the study. The fi rst type is jointed with bolt and nut on stiff ener or lipped, which is known as outstand stiff ener, and another type is connected by locating the bolt and nut on web element and recognised as extended stiff eners. The objective of the study is to determine the fl exural strength and load-deformation behaviour of both types of bolted built-up CFS section. Then, the experimental result is verifi ed with the Standard of Practice, American Iron and Steel Institute and BS EN 1993-1-3, Design of steel structures ( 2006 ). As a result, bolted built-up CFS beam with extended stiff ener and a span of bolt with constant value of 22.5 mm is expressed as a good result of fl exural strength. In addition, the fl exural strength of both beams is dependent only on spacing or bolt location.
