The main focus of this study is to ascertain the safety factor of a masonry tower in Aleppo, Syria under earthquake loading. Multiple types and level of analysis are performed to understand the behavior and capacity of the structure, starting from LVL1 Analysis until the 3D non-linear pushover with the help of commercial software (ABAQUS). However, before the 3D analysis is carried out, a preliminary check with simple model is conducted just to understand the capability of the commercial software in producing the desired result. Afterwards, a simplified 3D model with Concrete Damage Plasticity constitutive law is established to obtain the pushover curve. Along the analysis, some checks with simple assumptions are used to verify the validity of the result. The outcome from the pushover analysis will be used to verify the safety factor obtained through LVL 1 Analysis. Furthermore, the pushover analysis will also give an insight to the ductility of the tower, which will be compared to the ductility factor computed by means of manual calculation.
L'obiettivo principale di questo studio è di accertare il fattore di sicurezza di una torre in muratura ad Aleppo, in Siria sotto carico sismico. Vengono eseguiti più tipi e livelli di analisi per comprendere il comportamento e la capacità della struttura, partendo da un’analisi LVL1 per poi arrivare ad un modello 3D non lineare mediante l’utilizzo del software ABAQUS. Tuttavia, prima di procedere con l'analisi 3D, viene eseguito un controllo preliminare con un modello semplificato per comprendere la capacità del software commerciale di ottenere il risultato desiderato. Successivamente, viene realizzato un modello 3D semplificato con legge costitutiva Concrete Damage Plasticity per ottenere la curva di capacità dall’analisi pushover. Parallelamente all'analisi, per verificare l’attendibilità del risultato, vengono effettuati alcuni controlli con assunzioni semplificate. Il risultato dell'analisi pushover verrà poi utilizzato per verificare il fattore di sicurezza ottenuto tramite l'analisi LVL 1. Inoltre, l'analisi pushover fornirà anche una panoramica della duttilità della torre, che sarà confrontata con il fattore di duttilità ottenuto mediante calcolo manuale.

Abstract
The main focus of this study is to ascertain the safety factor of a masonry tower in Aleppo, Syria under earthquake loading. Multiple types and level of analysis are performed to understand the behavior and capacity of the structure, starting from LVL1 Analysis until the 3D non-linear pushover with the help of commercial software (ABAQUS). However, before the 3D analysis is carried out, a preliminary check with simple model is conducted just to understand the capability of the commercial software in producing the desired result. Afterwards, a simplified 3D model with Concrete Damage Plasticity constitutive law is established to obtain the pushover curve. Along the analysis, some checks with simple assumptions are used to verify the validity of the result. The outcome from the pushover analysis will be used to verify the safety factor obtained through LVL 1 Analysis. Furthermore, the pushover analysis will also give an insight to the ductility of the tower, which will be compared to the ductility factor computed by means of manual calculation.| File | Dimensione | Formato | |
