NHERI Tallwood: EQ performance of walls and windows
U of Nevada earthquake engineer Keri Ryan shows us the external wall units on the 10-story NHERI Tallwood building: spandrels with ribbon windows and glass curtain walls, called mullions. Architects as well as engineers want to see how such non-structural elements perform under earthquake loading. During the March 2023 shake table test, more than 750 sensor channels will record behaviors like drift, acceleration, and joint slip and movement.
