---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - This study presents a new method for 1.1 Cold-Formed Steel (CFS): constructing lightweight laminated walls by combining ColdFormed Steel (CFS) and Recycled Plastic Lumber (RPL). The aim is to create a structural system that leverages CFS's strength and RPL's lightweight, sustainable properties, making it suitable for various applications, from architectural projects to mobile structures.
Cold-formed steel is manufactured by shaping sheets of steel at room temperature through processes like roll-forming or pressing. Despite being lighter and more cost-effective compared to hot-rolled steel, CFS maintains robustness and dimensional precision suitable for various construction applications. In this integrated system, CFS components such as studs, joists, and panels play a pivotal role in reinforcing the laminated wall structure.
In this system, RPL blocks are strategically arranged and bonded with epoxy, then externally reinforced with CFS sheets to enhance structural integrity. Additionally, CFS components are incorporated internally in various patterns to optimize performance.
1.2 Recycled Plastic Lumbers (RPL): recycled plastic lumber is an environmentally sustainable alternative to traditional wood materials, composed of recycled plastics that contribute to reducing environmental pollution from plastic waste. rpl exhibits versatility in both nonstructural and structural applications, offering durability and resilience while promoting sustainable construction practices
The research focuses on investigating the axial compression and bending performance of three wall configurations: externally strengthened, internally strengthened, and a combination of both. The methodology includes a comprehensive literature review to establish a foundation of existing knowledge. Following this, model validation processes are conducted to ensure the accuracy of computational models developed using ANSYS software. These models simulate the behavior of the three wall types under different loading conditions.
1.3 Integration and advantages of the laminated wall system Enhanced Structural Integrity strategically is achieved by placing CFS components within the laminated structure— both externally laminating with CFS sheets and internally embedding CFS between RPL blocks—the wall system achieves enhanced load-bearing capacity and resistance to lateral forces.
The results from these simulations are thoroughly analyzed to identify the most effective configurations in terms of structural performance. This research advances the understanding of how CFS and RPL can be combined to create lightweight yet strong laminated walls. It aims to provide practical guidance for implementing these innovative structural solutions in real-world settings.
Environmental Sustainability by Utilizing RPL reduces reliance on virgin materials and minimizes the environmental footprint associated with traditional construction materials. This aligns with global efforts towards sustainable building practices and contributes to LEED (Leadership in Energy and Environmental Design) certification objectives.

1. INTRODUCTION ON LIGHTWEIGHT LAMINATED WALL CONCEPT A lightweight laminated wall typically incorporates multiple layers of materials strategically bonded together to optimize strength and durability while minimizing overall weight. Traditionally, materials such as plywood, foam, or composite panels are used in such systems to achieve a sturdy yet manageable structure. The integration of CFS and RPL introduces a novel approach by combining the benefits of steel and recycled plastics
