Cyclic Lateral Loading Behavior of Thin-Shell Precast Concrete Wall Panels
Sevil Yaman, Tuğçe
Two precast concrete thin-shell wall panels were subjected to reverse-cyclic lateral loads to simulate wind fatigue over a 50-year design lifetime prior to loading to failure. The panels consisted of an outer wythe of concrete connected to light gauge steel framing. Wire mesh was used to reinforce the concrete panel skin. Rivets provided a connection between the steel studs and the concrete panel. Two reinforced concrete (R/C) beams were integrated into the top and bottom of the panel, isolated from the concrete face by a thin layer of extruded polystyrene (XPS) foam insulation. Carbon fiber reinforced polymer (CFRP) grid was used to connect these beams with the concrete face through the rigid foam insulation. The objective of the testing program was to characterize the behavior of the con...
Customized Insulation Strategies for Türkiye: Life Cycle Cost Analysis and Impact on Business Competitiveness
Saygın, Muhammet | Say, Fuat Serkan | Öztürk, İsmail Yavuz
A significant portion of energy consumption in buildings is allocated to heating, with substantial losses resulting from inadequate insulation, poor sealing, and thermal bridging. While proper insulation plays a crucial role in mitigating these losses, determin- ing its optimal thickness is essential to reduce energy consumption and increase energy efficiency. This study employs life cycle cost analysis and average heating degree day values to calculate the optimum insulation thickness for 81 provinces in Türkiye. The findings highlight the absence of a one-fits-all insulation solution, emphasizing the need for customized approaches tailored to specific conditions that consider specific factors, such as environmental conditions, heating sources, costs, economic parameters and the materials...
