“…Balok lebar memiliki inersia rendah sehingga desainnya memerlukan tulangan yang besar untuk memikul momen yang bekerja. Hal ini membuat desain kolom juga berpengaruh terkait dengan aturan kolom kuat balok lemah, walaupun secara kekakuan telah memenuhi persyaratan (Benavent-Climent, 2007;Climent et al, 2008;Fadwa et al, 2014;Mirzabagheri et al, 2018). Pengamatan secara numerical menunjukkan peningkatan mutu beton tidak memberikan pengaruh significant pada join balok lebarkolom (Mirzabagheri et al, 2018).…”

A reinforced concrete frame building system using wide beams is a solution for buildings with limited heights to get a larger number of stories, a higher distance between stories, and flexibility in installing architectural elements and MEP. This analytical study was conducted to evaluate the behavior and performance of open-frame structures with wide beams for one-way and two-way slab system conditions. This study was carried out using a structural analysis program by applying linear and nonlinear analyzes to four models of a five-story structure with square columns, which varied in beam dimensions and slab systems. The variations considered are normal beam with one-way slab system (1wSN), normal beam with two-way slab system (2wSN), wide beam with one-way slab system (1wSW), and wide beam with two-way slab system (2wSW). All structural elements are designed to follow and meet the criteria of the Indonesian Building Codes, which are then followed by a non-linear static pushover analysis to obtain the performance of each structural model. The results of the analysis show that a structure with wide beams has greater deformation than a structure with normal beams with a faster achievement of collapse conditions so that the ductility of the structure also becomes lower. This is caused by the stiffness of the wide beam-column joints is lower than that of the normal beam-column joints. The use of one-way or two-way slab systems on structures with wide beams does not have a significant effect

“…Various researchers did numerical modelling of reinforced concrete structures because of its power in studying various types of structures [13,14] . However, it is strongly suggested that experimental results be used to validate computer models and then the validated models be used to simulate the behaviour of structures.…”

Glass fibre-reinforced polymer (GFRP) has been increasingly used as the main reinforcement in concrete structures due to its durability and resistance to corrosion. However, there is a lack of data regarding the bond behaviour of GFRP bars with 180-degree hooked ends used in flexure concrete elements. To investigate the effects of the hooked ends of GFRP bars on the bond strength with concrete, beams reinforced with GFRP bars with straight and hooked-end lap splices at the midspan were modelled using ABAQUS/Standard software. The finite element models were validated using the experimental results of four full-size concrete beams. Two beam specimens had straight-end bars, while the other two had hooked-end bars. Sensitivity analysis was performed to find the proper values for model verification, such as dilation angle and mesh density. According to the outcomes of the parametric study conducted in this research, changing the length of the bar lap splices in the range of 15 to 40 times the bar diameter had a negligible effect on the beam’s overall behaviour. Increasing the number of reinforcing bars from 3 to 5 increased the beam flexural strength by about 33%, whereas increasing the diameter of the bars from 10 to 20 mm doubled the beam strength.

“…One of the most popular smeared crack concrete models is the concrete damage plasticity model (CDP), proposed by Lubliner et al [29], developed by Lee and Fenves [30], and implemented in ABAQUS [31]. Because of the high computational cost of nonlinear analysis of RC structures, especially for fine mesh sizes between 25 mm and 12.5 mm [32][33][34], many researchers [35][36][37][38][39][40] successfully obtain the detailed behaviors of different structural elements tested under cyclic loading (i.e., load-displacement backbone curves, cracking patterns, yielding in reinforcement bars) by adopting monotonic loads through the CDP model. On the other side, several researchers [41][42][43][44][45][46] failed to obtain the cyclic characteristics of different structural responses for elements modeled via CDP even at a 30 mm mesh element size [47].…”

Over the last century, the seismic behavior of reinforced concrete (RC) beam–column joints has drawn many researchers’ attention due to their complex stress state. Such joints should possess sufficient capacity and ductility to ensure integrity and safety when subjected to cyclic loading during seismic events. In the literature, while most studies have focused on the behavior of concentric beam–column joints, few studies investigated the response of eccentric beam–column joints, in which the beam’s centerline is offset from the centerline of the column. Recent earthquakes demonstrated severe damage in eccentric beam–column joints due to their brittle torsional behavior, which may threaten the ductility required for the overall structural performance. To investigate the effect of brittle failure on the strength, ductility, and stability of eccentric beam–column joints, nonlinear finite element (FE) models were developed and validated. The FE model was employed to study the effect of some geometric parameters on the global and local behaviors of beam–column joints, including the joint type (exterior and interior), the column aspect ratio, and the joint aspect ratio. The results show that the joint aspect ratio, which is the ratio of beam-to-column depth, has a predominant effect on the failure behavior of the joint. Additionally, the increase in column aspect ratio alters the failure mode from brittle joint shear failure to ductile beam-hinge, although there is an increase in the joint torsional moment. The current study also showed that interior joints exhibited a higher out-of-plane moment as well as more extensive column torsion cracks compared to exterior joints.
