Abstract:
This paper describes the experimental testing of a reinforced
concrete tessellated shear wall. The wall specimen was tested as part
of a National Science Foundation-funded research project designed
to demonstrate the concept of tessellated structural-architectural
(TeSA) systems. TeSA systems are constructed of topologically
interlocking tiles arranged in tessellations, or repeating geometric
patterns. As such, these systems are designed with easy repair and
reuse in mind. The specimen discussed in this paper is a TeSA shear
wall constructed from individually precast I-shaped tiles. This
paper presents the results of reverse cyclic loading of the specimen,
including load-displacement behavior, crack propagation, and
energy dissipation. A simplified analytical model for predicting the
wall’s flexural capacity is also discussed.
