“…To evaluate the mechanical properties of the resulting PP/HDPE polymer composites, tensile and flexural tests were performed using a SHIMADZU AGX-V universal testing machine with a 5 kN load cell, following ASTM D638-03 [53] (Type IV) and ASTM 790 [54] standards [55]. The tests allowed us to determine mechanical properties of the composites, such as elastic modulus, maximum stress, and maximum deformation.…”

“…To better understand the mechanical properties of the resulting PP/HDPE polymer composites, five specimens were tested under controlled conditions. This included tensile and flexural tests performed using a SHIMADZU AGX-V universal testing machine with a 5 kN load cell, following ASTM D638-03 (Type IV) and ASTM 790 standards [55]. Each specimen was securely positioned within the grips of the testing machine to ensure uniform application of force and to prevent slippage.…”

This study aimed to investigate the sustainable use of recycled plastics, specifically polypropylene (PP) and high-density polyethylene (HDPE), in the manufacture of geogrids for geotechnical and civil engineering applications. Plastics were collected from a recycling center, specifically targeting containers used for food, cleaning products, and other domestic packaging items. These plastics were sorted according to the Möbius triangle classification system, with HDPE (#2) and PP (#5) being the primary categories of interest. The research methodologically evaluates the mechanical properties of PP/HDPE (0/100, 25/75, 50/50, 75/25 and 100/0% w/w) composites through tensile and flexural tests, exploring various compositions and configurations of geogrids. The results highlight the superiority of pure recycled HDPE processed into 1.3 mm thick laminated yarns and hot air welded for 20 to 30 s, exhibiting a deformation exceeding 60% in comparison to the PP/HDPE composites. Through SolidWorks® Simulation, it was shown that the adoption of a trigonal geogrid geometry optimizes force distribution and tensile strength, significantly improving slope stabilization efficiency. Based on the results obtained, a laboratory-scale prototype geogrid was developed using an extrusion process. The results underscore the importance of careful composite design and yarn configuration selection to achieve the desired mechanical properties and performance in geogrid applications. It emphasizes the potential of recycled plastics as a viable and environmentally friendly solution for stabilizing slopes, contributing to the reduction in plastic waste and promoting sustainable construction practices.

“…Performance-based procedures play a vital role in the structural response of high-rise buildings to seismic forces; hence columns are designed to maintain a certain level of damage under the influence of the load applied to resist collapse. According to Rochman et al, the level of damage in the column is usually related to moment capacity, drift capacity ratio, and drift ratio during yielding conditions [14]. A Braced-Frame Structure (1) supports the exterior columns of a rigid frame by using them as web members in the vertical truss system along the exterior.…”

This study is concerned with reviewing and analyzing methods used in early design stages to mitigate wind effects on high-rise buildings. In order to mitigate wind effects on structures and specifically high-rise buildings, early stage aerodynamic design decisions are made. Architects try to mitigate the wind effects on buildings by choosing the right form configuration like tapering or setbacks, etc., or by making vital decisions in the early design stage. However, structural engineers utilize the structural system that can best counter-act forces acting on the stability of the building. For both architects and engineers there are many tools which can be used in early design including advanced analysis methods, wind tunnel testing and wind studies combined with Computational Fluid Dynamics (CFD) simulations. This study reviews general architectural and structural design configurations performed in the early phases of the design process, for achieving structural stability, comfort and cost control. The research methodology depends on the study and analysis of different international building examples, and also by reviewing two local high-rise building cases in Amman, Jordan. The study concludes that there are many architectural aerodynamic configurations for the purpose of mitigating wind loads, which can be used as guidelines in the early design phases.

“…On the other hand, with the increasing demand for the erection of high-rise structures, the structural elements that consist of these buildings require to have high strength with efficient mechanical properties. The column is one of the most crucial structural elements that play an essential part in transporting vertical and transverse loads, especially on the lower floors since it experiences high vertical loads [8][9][10], also the philosophy of building design requires that the failure should occur in beams before columns (weak beam-strong column theory) [11]. This necessitates finding new techniques that improve structural performance in regard to strength, stiffness, and ductility, especially in areas exposed to seismic activity.…”

In this study, an innovative reinforcement technique is proposed to augment the structural performance of reinforced concrete (RC) columns. The technique involves the introduction of inclined steel ties (bracing reinforcement), connecting longitudinal steel rebars on one side of the square column cross-section at a tie with the longitudinal rebar on the opposite side at the next lower tie. These inclined ties form with the conventional ties and longitudinal rebars a truss structure. The introduced bracing reinforcement effectively enhances the bracing of longitudinal rebars, resulting in substantial improvements in the strength and ductility of RC columns. The study investigates three key parameters using finite element analysis: the pattern of bracing reinforcement, the number of bracings along the column height, and the application of bracing reinforcement under eccentric loading conditions. The findings demonstrate a significant enhancement in yield and ultimate load, stiffness, and ductility of RC columns utilizing this novel technique. Specifically, employing two bracing reinforcements on opposing sides of the column yields the most remarkable structural performance improvement, manifesting in a 32.2% increase in yield load, a 38.7% increase in ultimate load, and a 60.7% augmentation in ductility ratio. Moreover, the study reveals a proportional increase in structural performance improvement with an escalation in the number of bracings within the column height. However, when employing bracing reinforcement under eccentric loading, a reduction in the gain of ultimate strength and ductility, and a corresponding rise in the gain of yield load are observed in comparison to concentric loading conditions.
