At EESD, we have developed an analytical model to capture the flexural response of vertically spanning out-of-plane loaded URM walls. Developed using the second-order Euler-Bernoulli beam theory, this model effectively represents key aspects of these walls’ response, previously observed in experiments and numerical studies but lacking a theoretical explanation. These aspects include the initial development and progression of cracks, the maximum strength of the walls under load, and the reduction in response strength due to P−Δ effects. The model’s accuracy is confirmed by comparing it with experimental data, showing its ability to accurately predict the walls’ behavior both before and after reaching their peak strength.
