This led to the general application of Round Hollow Structural Section (Round HSS) as column and beam elements. Therefore, this study aimed to conduct parametric analysis of the effect of Diameter-to-Thickness Ratio (D t -1 ) on the three-point and four-point flexural analysis of Round HSS beam using MSC Marc/Mentat software. Nonlinear materials and geometries were employed, along with the application of contact analysis, with contacted and contacting bodies. Moreover, the load and boundary condition were set to be similar to the experiment. The results showed that a greater D t -1 led to the possibility of withholding a smaller load and causing smaller displacement in Group A with fixed diameter and different thickness values. Meanwhile, in Group B with fixed thickness but different diameters, a greater D t -1 led to the potential of restraining more load and experiencing smaller displacement. All specimens from both groups were observed to have failed due to a combination of global and local buckling at the right location under the load applied. AISC bending moment calculated was found to be greater than the values obtained from the finite element analysis for all sections under three-point loads. It was also discovered in the four-point flexural analysis that the bending moment of noncompact section was greater than for AISC while those for the compact section were lower. Furthermore, shear strength (Vn) calculated was observed to be greater than shear force from finite element analysis (Pmax/2).

Nevertheless, reinforced concrete standard code (SNI 2847:2019) not emphasized a specific method to calculate the concrete-steel deck slab's nominal capacity. The code is embraced by the plastic method analysis, which is calculated the nominal capacity of the structure on the ultimate condition. However, several laboratory tests reveal a slip behavior between the concrete and steel deck before the slab reaches its ultimate condition. Therefore, alternative methods are needed to analyze the nominal capacity of concrete-steel deck slab. This study compares three different nominal capacity analysis methods to a laboratory test result. Those methods are ultimate, working stress, and SDI-ANSI (2017). The average error value of those three methods compared to laboratory test results in 35,57%, 9,48%, and -10,31% fo...
