“…The next step is to determine the design curvature of the shear walls. There are two design conditions: First, to design on serviceability conditions s = 0.0175 / lw (7) Second, to design in a damage control state s = 0.072 / lw (8) The length of the plastic hinge in the shear wall is determined by ( 9) and (10).…”

Shear walls' placement in specific positions could develop different structural responses to the building and affect the structure's strength to the received lateral loads. This research aims to find the variations in the shear walls' placement on the structure's response under the Direct Displacement Based Design (DDBD) method. The object of this research is the model of a 10-story reinforced concrete building located in Yogyakarta, Indonesia. Modelling of building structures is carried out in this study with four variations of shear wall placement. First, the walls are located at every building's corner. The shear wall is then positioned in the core of the building, where the apertures have shrunk. Then, the shear wall is located on the edge of the building. Last, the shear wall is located on the edge of the building. ANOVA method is used to analyze the significant difference, i.e., variations in the walls' placement. This research indicates the significant differences in the x-direction shear force and the y-direction moment The shear walls are suggested to be placed according to the building's condition and the earthquake ground site's class to produce an optimal structure to resist earthquake loads.

“…However, the beams and columns will be pretty significant when the building is designed without shear walls, and problems will arise at the joints [5]. Furthermore, the presence of the shear wall will affect the building's stiffness so that the lateral forces are not fully borne by the frame structure (columns and beams) [6] [7].…”

“…Some parametric studies of CB with circular and diamond-shaped openings were carried out. In [6], the study was performed to optimize its size by considering the ratio of the overall depth of the castellated beam to the depth of opening provided (D/Do) and the ratio of spacing of opening to the depth of opening (S/Do). From their study, they concluded that the CB gives good flexural strength results for the diamond-shaped opening with a size of 0.67 times overall depth of the beam.…”

Using modern technologies for fabricating steel, I-beams can be easily made by welding, and hot-rolled beams can often be produced at an economical price with slender webs and equal flanges. Experimental and theoretical studies of the behavior of tapered castellated steel beams were carried out. Due to the cost reductions associated with tapered castellated steel beams, they are a feasible alternative to prismatic components. This study assessed the influence of tapered castellation on the bending capacity and flexural stiffness of tapered castellated steel beams (TCBs) with simply supported end conditions experimentally and theoretically. Four three-point bending tests on TCBs with H/h values of 1, 1.2, 1.4 and 1.6 were conducted utilizing a standard parent I-section beam (IPE140) as the control specimen. The test findings include the ultimate load vs. mid-span deflection response curves and failure mechanisms. The testing findings indicated that the TCBs' ultimate load capacity might be up to 140 percent of that of the parent section. The Abaqus program was used to conduct a finite element (FE) analysis of TCB, which allows for material and geometric nonlinearity. The derived finite element models exhibit excellent agreement with the experimental results in terms of ultimate load capacity vs. mid-span deflection response and failure mechanisms. Based on the results of the work, TCBs can be used for increasing the strength and stiffness of the I-section parent beam with adding expansion plates. The maximum load capacity of TCBs can be enhanced when adding expansion plates up to 40 % above that of the parent beam. A TCB has lower ductility than its parent beam. Moreover, a TCB fulfills serviceability requirements since its mid-span depth exceeds that of its parent beam.

“…Steel is a highly durable and resistant material, and the high strength-to-weight ratio of steel enables it to result in a high load-carrying capacity. A lot of advantages are found such as the strength uniformity, specific sizes from the manufacturer so that the section can be easily fabricated and it has high yield strength for both compressive and tensile strength (Maulana et al , 2019). Structural steel sections are more concerned due to its material that can be produced with various shapes and properties (McKee, 2021; AISC, 2018) and I-beam is the most commonly used steel section (Brakefield, 2020).…”

Purpose Due to the enormous increase in economic development, structural steel material gives an advantage for the construction of stadiums, factories, bridges and cities building design. The purpose of this study is to investigate the behaviour of bending, buckling and torsion for I-beam steel section with and without web opening using non-linear finite element analysis. Design/methodology/approach The control model was simulated via LUSAS software with the four main parameters which included opening size, layout, shape and orientation. The analysis used a constant beam span which is 3.5 m while the edge distance from the centre of the opening to the edge of the beam is kept constant at 250 mm at each end. Findings The analysis results show that the optimum opening size obtained is 0.65 D while optimum layout of opening is Layout 1 with nine web openings. Under bending behaviour, steel section with octagon shapes of web opening shows the highest yield load, yield moment and thus highest structural efficiency as compared to other shapes of openings. Besides, square shape of web opening has the highest structural efficiency under buckling behaviour. The lower buckling load and buckling moment contribute to the higher structural efficiency. Originality/value Further, the square web opening with counter clockwise has the highest structural efficiency under torsion behaviour.
