“…Due to the demand for increased construction space on sites, labor constraints, prolonged waiting times for concrete curing and hardening, and shortcomings in quality control, traditional cast-in-situ construction is gradually being replaced by the widespread adoption of precast concrete systems. However, precast concrete structures pose specific challenges, particularly in terms of lateral bracing [19,[22][23][24][25]. While they exhibit numerous similarities to cast-in-place concrete structures, they lack the inherent member-to-member continuity that imparts significant lateral stability [26].…”

“…The dual-system reinforcement incorporates the main reinforcement with a truss system embedded in the column to enhance its resistance to lateral forces caused by wind and earthquakes [31]. Three-dimensional finite element simulation was used to investigate the displacement of the prototype model of a 1:5 scaled IBS cruciform column [23,24,[31][32][33]. IBS cruciform column specimens were modeled and analyzed linearly using LISA software [36].…”

Throughout history, the construction industry has been a significant contributor to construction waste, presenting an ongoing challenge in efficiently managing this waste to mitigate environmental pollution. The Industrialized Building System (IBS) stands out as a construction approach that utilizes prefabricated components made from various waste materials, implemented with machinery and formwork, leading to minimal waste production. The potential failure of IBS blockwork columns under lateral loads is a significant concern, and the deformation of these columns is crucial in assessing overall structural performance against lateral forces. This study focuses on examining the deformation and flexibility of components in IBS blockwork columns when subjected to lateral loads. Using Finite Element Modeling (FEM), a 1:5 scale prototype model of the dual-reinforced system IBS Block Work Column is analyzed. The IBS Block Work Column, comprising four prefabricated components assembled in the form of a crucifix plan to enhance lateral stability, is subjected to FEM analysis and experimental investigations. The study aims to explore the impact of four different shapes of reinforcement on deformation resistance. The findings suggest that employing a dual-reinforced system in the IBS Block Work Column enhances its resistance to lateral loads compared to a column with conventional reinforcement. Moreover, the assembled IBS Block Work Column exhibits greater stiffness than a single prefabricated component when subjected to lateral loads. Doi: 10.28991/CEJ-2024-010-01-020 Full Text: PDF

“…Many scholars have carried out experimental and numerical programs in order to analyze the performance of concrete sandwich walls under various loading conditions [4][5][6][7][8][9][10][11][12][13][14]. Among them, Xu et al [5], Rao and Poluraju [8] and Xue et al [9] performed experimental investigations on concrete sandwich wall panels in order to analyze their seismic performance. Lee and Pessiki [6] and Yu et al [11] analyzed the thermal behavior of the concrete sandwich walls based on experimental and numerical approaches.…”

Bending Performance of Concrete Sandwich Walls with Actual Boundary Conditions

et al. 2023

Concrete sandwich walls are commonly used as the exterior wall panels of a structure, in which the wall suffers out-of-plane bending under strong wind conditions. This paper aims to investigate the bending performance of concrete sandwich walls under actual boundary conditions through experimental and analytical methods. In total, four concrete sandwich walls were tested to detect the influence of openings and loading direction. Typical failure patterns were characterized and discussed. The load-displacement curves of four test specimens were analyzed. It was indicated that the bearing capacity of the walls under negative bending conditions was higher than that under positive bending conditions, owing to the additional constraints provided by the steel beams. Strain distributions of wall specimens were also discussed in order to obtain the composite action of the sandwich walls between the upper and lower layers of concrete. In addition, the finite element model (FEM) was developed by ABAQUS to provide insights into the bending performance of the sandwich walls. Through comparison with the test results, the FEM was verified with a good level of accuracy. Subsequently, the degree of composite action of the sandwich walls was assessed in terms of both the moment of inertia and bearing capacity. From the experimental and numerical results, it demonstrated that the bearing capacity of concrete sandwiched wall under negative direction was higher than that under positive direction owing to the constraints of steel beam. The derived composite action degree could be employed to evaluate the out-plane bending stiffness and strength of sandwiched concrete wall. Both the experimental and analytical results in this paper are beneficial for the design of sandwich walls under bending conditions.

A new precast hollow insulation shear wall (PHISW) is proposed in this paper. To study the seismic behaviors of the new PHISW, two cast-in-place solid shear wall (CSW) specimens, two precast monolithic hollow insulated shear wall (PMW) specimens, and two precast hollow insulated shear wall (PSW) specimens with vertical seams were produced and subjected to low-cyclic reversed loadings. The seismic indices obtained from low-cyclic reversed tests include the failure pattern, hysteretic curves and energy dissipation. The experiment results indicate that flexural failure is the main failure mode of the specimens, but a noticeable difference is detected in the cracking distribution between the three types of shear walls. The bearing capacity of each characteristic point of PMW and PSW is comparable to that of CSW. The ductility coefficient of the newly proposed precast shear wall is slightly lower than that of CSW.
