DATA srlThe local verification enviroment within 3Muri Project software is powerful to design facilities and to verify multiple structural elements such as beams, columns, floors, walls, footings, arcs and many more. One of the key advantages of the local verification enviroment is its versatility. Whether you’re working on a new project or refine system design, the software enables seamless integration in the model. This means that changes made within the structure environment can be instantly reflected in the local verification environment ensuring consistency and coherence throughout the design process.

The main industrial activities that generates earthquakes are the following: hydrocarbons storage and extractions, shale gas exploitations, geothermal energy exploitation, mining operations, CO2 sequestration, dams.
Typical buildings are reproduced in the Eucentre laboratories and in the Lisbon laboratories to highlight the crack progression of these type of existing buildings subjected to seismic actions.
Models calibrated with numerical studies were used to design the seismic improvement intervention of the buildings with 3Muri software.

3Muri Project: Seismic assessment strategies for masonry structures
This text discusses case studies focusing on the seismic assessment of existing masonry structures, particularly emphasizing the estimation of the magnitude of masonry walls and the significance of diaphragms in seismic analyses. It presents a procedure to determine the appropriate type of analysis—either a global analysis or single-wall analyses—based on the building’s characteristics. Additionally, it highlights the functionality of the 3muri project software, which facilitates single-wall analysis and enables a mixed approach to building design and verification.

3Muri Project: Seismic assessment strategies for masonry structures
In the realm of seismic assessment for existing masonry structures, case studies play a pivotal role. They provide invaluable insights into estimating the magnitude of masonry walls, a crucial aspect in seismic analyses. Additionally, the significance of diaphragms cannot be overstated in such assessments. They serve as key components in seismic analyses of masonry buildings, contributing significantly to their structural integrity.
The presented procedure outlines a systematic approach for determining whether global or single-wall analyses are more suitable for a given scenario. This criterion aids in making informed decisions regarding the most appropriate analytical method to employ. Notably, the 3Muri Project emerges as a valuable resource in this domain, offering the capability to conduct detailed single-wall analyses and effectively model mixed buildings. Through its advanced features, the project enhances the accuracy and reliability of seismic assessments, thus facilitating informed decision-making in structural engineering and urban planning.

Bruno Arias Van Lierde - Technical Expert S.T.A. DATA ENG/by Nicolò3Muri Project Open Introduction
The 3Muri Project OPEN specializes in the analysis of buildings that deviate from conventional box-like structural behavior. These structures, often characterized by their unique architectural designs or historical significance, pose particular challenges in terms of seismic vulnerability assessment. By leveraging the advanced capabilities of OPEN, the project enables comprehensive calculations of seismic risk for such buildings. Through non-linear kinematic analysis conducted at limit states, the project offers a nuanced understanding of the structural integrity and performance of these buildings during seismic events. Particularly noteworthy is the project’s ability to conduct in-depth evaluations of both in-plane and out-of-plane kinematic behavior of masonry structures lacking traditional horizontal elements.
A compelling demonstration of the project’s methodologies and findings is provided through a captivating real-life test showcased in a video. This video features a venerable church, emblematic of the architectural heritage prevalent in many historical contexts, yet notably devoid of the typical horizontal structural elements found in modern constructions. By showcasing the application of 3Muri Project OPEN’s analytical techniques to this ancient edifice, viewers gain insight into the complexities of preserving and retrofitting historical buildings to withstand seismic forces effectively. Through its innovative approach and meticulous analysis, the project contributes valuable knowledge and methodologies essential for enhancing the seismic resilience of diverse architectural treasures worldwide.
