Abstract

A novel precast eco-efficient structural wall with high durability was recently proposed. To advance this research, three dry-bolted connections were developed to facilitate the lateral assembly of this wall system. To evaluate the performance of this structural wall system with bolted connections, monotonic shear loading tests were conducted both in-plane and out-of-plane. This paper provides a detailed description of the three bolted connections, the test specimens composed by two walls assembled using the three different connections and the experimental setup. The results from multiple tests are presented and analyzed. Key conclusions are drawn, and practical design recommendations are also provided.
