Which system requires a minimum thickness of 6 inches for horizontal and vertical concrete members?

The correct answer, referring to the system that requires a minimum thickness of 6 inches for horizontal and vertical concrete members, pertains to the Screen-grid Wall System. This system is specifically designed to provide structural integrity while also accommodating thermal performance and other building requirements.

In a Screen-grid Wall System, the configuration of concrete members typically results in the necessity of maintaining a minimum thickness of 6 inches. This thickness is essential to ensure adequate strength and stability, especially when considering the loads and stresses that the wall may encounter throughout its lifecycle. The distributed load-bearing capacity of the concrete also improves with this minimum thickness, promoting overall building safety and durability.

While other systems might incorporate different minimum thickness criteria based on their specific applications, the Screen-grid Wall System is structured to leverage this 6-inch thickness to enhance performance. Understanding the unique characteristics of each wall system is important for performing inspections and ensuring building code compliance.
