Abstract

This research presents the result of two rectangular filled tube column-to-beam connections under cyclic loading using finite element analysis. Connections of all two models were using weld connection and shear tab attached to beam webs. In this study, 2 models were made: RR-1 and RB-2, which are RCFT connection with RBS and RCFT connection without RBS. This study is conducted to learn, the advantages of RCFT connection with RBS against RCFT connection without RBS. The analysis results observed that cyclic performance of the RBS moment connection was much superior to the connection without RBS. The highest regions of stress occur in vicinity of beam bottom flange near column face for connection without RBS. For connection with RBS, the highest regions of stress occur in reduced beam section of the beam

Abstract

The paper disccuses an analysis study on the design of Eccentrically Braced Frame (EBF) i.e. short link, intermediate link and long link) with K-Braces-type Split 1 floor. The analysis is performed by using ABAQUS with static monotonic loading in a single structure (frame). Each element of the frame is modeled as sholid 3D with connections to every element in the form of tie constraints and given fixed on each base of the column as a boundary condition. All three models of the frame has been analyzed in accordance with the AISC 2010 provisions and then compared the behavior of each of these models. The results indicate that the short link model considered in this study have on a higher over strength value and used as a proposed model when compared to intermediate link and long link model. It is stated by the failure mechanism as well, the failure is well-occurred in the short link condition than the other models

Abstract

The warehouse frame is a specialized steel structure requiring more complexcalculations than standard portal frames. This study investigates the impact ofrafter angle and span length on ductility and stability. Results indicate thatincreasing span length enhances ductility but reduces stability due to higher storydrift. For example, M1 (10-meter span) shows a ductility of 4.62 and story drift of13.64 mm, while M3 (20-meter span) achieves 5.07 (+9.62%) with a drift of 46.77mm. A larger rafter angle slightly increases ductility but decreases stability. M1 (10°angle) records 4.62 ductility and 13.64 mm drift, whereas M7 (20° angle) reaches4.71 (+1.79%) with 16.92 mm drift. Higher structure stiffness reduces ductility butboosts stability. M3 (128.29 kN/m stiffness) shows 5.07 ductility and 46.77 mmdrift, while M12 (192.67 kN/m) records 4.96 (-2.17%) with 29.68 mm drift. DespiteM12's minor ductility reduction, M3 demonstrates better elastic-plastic behavior.These findings reveal a clear polarity between ductility and stability.

Abstract

In half-through bridge or pony steel bridge, that is a bridge without upper windbracing, strength of the bridge is determined mainly by the lateral bucklingstrength of its upper chord. Buckling strength of this chord is provided by theflexural stiffness of vertical web member, cross beam, and diagonal beam. In orderto improve the stiffness of vertical web member, triangular steel profile that wasquite high was added to the inner side of bridge for reducing the clearance widthin bridge and disturbing traffic or pedestrian. In this research, stiffness of thevertical web member was improved by using the non-prismatic cross section andadding the triangular stiffener as high as the concrete deck. Finite ElementAnalysis for the lateral stiffness of bridge cross section used a 3D element modelwhich has been validated by previous study. This numerical study was conductedto validate the Engesser theory for determining the lateral elastic stiffness fromupper chord. Study shows the result that accuracy of 3D element model isextremely high, compared with analytic method. Lateral elastic stiffness of bridgein general increased along with the stiffness of vertical web member. However, itcan be concluded that effect on the capability of lateral buckling in upper chordwas not too significant, as a consequence of the increase in stiffness of verticalweb member. Critical lateral buckling occurred in an inelastic range, in which thecritical inelastic buckling stress was determined using small tangent modulus asalternative of modulus of elasticity.

Abstract

Various types of structural technology began to develop rapidly, one of which was composite steel. Composite steel (Concrete Filled Steel Tube) is a structure consisting of two or more materials with different material properties and form one unit so as to produce better combined properties. Compared to conventional steel, this column has many advantages such as convenient formwork for concrete cores provided by steel tubes, increased strength and good ductility. This study uses the CFT column as the main variable by considering variations in the CFT column on the connection using ABAQUS. Modeling was carried out with a test object of 203 × 133 × 7.8 × 5.8 mm and the CFT column dimensions of rectangular 220 × 220 × 6 mm, and circular Ø 220 mm t = 8 mm. The research method uses two steps static-general method with static-risk. The results of these two research methods have the results of approaching and having the same behavior. Modeling has fulfilled the requirements of modeling the column-beam joints that can be used in a system of earthquake-resistant reinforced steel composite concrete frame structures. Based on the modeling results that have been done, modeling has fulfilled the connection that has sufficient ductility capability.
