A series of static and shake table tests were conducted on pressurized threaded, brazed and mechanical, i.e., grooved pipe joints, commonly used in fire protection systems. The objective of the tests was to understand the behavior and failure modes of these common types of joints under seismic and static lateral loads. The paper presents the measured loads and deflections of the joints up to the point of failure. It also describes the joints’ static and dynamic failure modes. While this information may be limited it can be used to model the joint flexibility under large lateral loads, determine their capacity, and help understand the leak and rupture characteristics of threaded, brazed and clamped joints.
