Chang, L. (author)Investigations on unreinforced masonry (URM) walls subjected to natural hazards, such as earthquakes and wind loads, identify the out-of-plane (OOP) failure as one of the most common failure mechanisms. Concerning the OOP failure, two types of failure mechanisms can be distinguished in URM walls: one-way bending in which lateral edges of walls...doctoral thesis 2022

(author)A good bond between the layers of 3D printed cementitious materials is a prerequisite for having high structural rigidity for the printed elements. However, the influence of printing process on an interlayer bond is still not well understood. This study investigates the influence of curing methods (i.e., air curing, plastic film covering, wet...journal article 2022
