The results show that the values obtained with the simplified formula are very close to the values obtained by pushover analysis, especially if higher compressive strength values are assumed, and the scatters assume greater values as the irregularity in the arrangement of the openings in the vertical and horizontal direction increases. © 2022 The Authors.

To this aim, the panels of Convent of San Carlo all’Arena in Naples has been analyzed via nonlinear static analysis. The resu lts have been compared with the values provided by the application of the proposed simple expressions, which only depend on geometrical parameters and external loads. str ct I t is a er, a si le e ressi f r re icti t e riz tal ca acit f ltist re rei f rce as r fra es is r se a isc sse i t e fra e r f li it a al sis a r ac . t is ai , t e a els f e t f a arl all’ re a i a les as ee a al ze ia li ear static a al sis. e res lts a e ee c are it t e al es r i e t e a licati f t e r se si le e ressi s, ic l e e XIX ANIDIS Conference, Seismic Engineering in Italy Proposal of a simple expression for predicting the horizontal capacity of masonry walls Sorrentino P. a *, Brandonisio G. a , De Luca A. a a Dept. of Structures for Engineering and Architecture, University of Naples Federico II, Piazzale Tecchio 80, 80125 Naples, Italy i i t l rr ti . a , i i . a , Lu . a a ept. of Structures for ngineering and rchitecture, niversity of aples ederico II, iazzale ecchio 80, 80125 aples, Italy f , i i i
