An elastoplastic constitutive model within the framework of bounding surface plasticity theory is adopted to predict the mechanical behaviour of soft sandstone under monotonic and cyclic loadings. In this model, the loading surface always passes through the current stress state regardless of the...

Mojtaba Rahimi, Dave Chan, Alireza Nouri, Rouzbeh Rasouli
Sand response changes with intensity of cementation bonds between sand grains, magnitude of intermediate principal stress and with fabric anisotropy. First a critical state bounding surface plasticity model is presented in this paper. In this constitutive model, the loading surface always...

Field investigation and performance-based seismic design of rocking shallow foundations in cohesive soil
DownloadFall 2019
This research investigated the use of rocking shallow foundations in improving the seismic performance of soil-footing-structure systems. A series of lateral loading tests of large-scale rocking foundation systems in natural cohesive soil were conducted and a performance-based seismic design...

Shear Strength of Partially Grouted (PG) Masonry Shear Walls: Experimental and Analytical Studies
DownloadFall 2023
When subjected to in-plane loads, the shear behaviour of partially grouted (PG) masonry shear walls is complex due to the heterogeneous and anisotropic nature of the masonry materials and the nonlinear interactions among their constituents. For instance, insufficient shear strength will lead to a...
