4. Conclusion In this paper, starting from the previous study on the single portal frame, a formula to predict the horizontal capacity of masonry walls through the Limit Analysis approach is proposed. Such a formula only depends on geometrical parameters and external loads. To validate the formula, it has been tested on some panels of San Carlo all’Arena Convent in Naples and the results have been compared with the values provided by the nonlinear static analysis. The comparison shows that the values obtained with the simplified formula are very close to the values obtained by pushover analysis and the scatters assume greater values as the irregularity in the arrangement of the openings in the vertical and horizontal direction increases.
