Metodologias inovadoras no cálculo sísmico de estruturas em alvenaria simples e...

Tese de doutoramento em Engenharia Civil (área de especialização em Estruturas) ; As construções em alvenaria representam uma parte importante do legado construído e cultural do passado, mas também uma solução sustentável para o futuro. Esta é a principal premissa que motivou este trabalho, assim como o desenvolvimento significativo verificado na indústria de produtos para alvenaria nos últimos anos, apesar do...

A model for pushover analysis of confined masonry structures : implementation a...

Confined masonry (CM) is a typical building technique in Latin American countries. This technique, due to its simplicity of construction and similarity with traditional practices of reinforced concrete building, presents a potential of use in European regions with moderate-to-high seismicity. However, most of the procedures for seismic design in codes for Latin America are force-based, which appears to be inade...

Study of the seismic behavior of the “Old Municipal Chambers” building in Chris...

This paper presents a study of the seismic behavior of the “Old Municipal Chambers” building in Christchurch, which was damaged by earthquakes in 2010 and 2011. In view of its seismic vulnerability and retrofitting, finite element and equivalent frame models were used for pushover analysis. Predictions allow identifying the weak parts of the building and its expected failure modes, which are in agreement with t...

Verificação da segurança sísmica de edifícios em alvenaria através de metodolog...

Este artigo introduz conceitos de base para o cálculo sísmico de edifícios sustentáveis em alvenaria simples de pequeno porte (até 2 pisos), usando metodologias de análise estrutural a nível global e simplificadas. Estas metodologias, ainda que relativamente simples e passíveis de utilização através de um cálculo manual, foram desenvolvidadas em países com sismicidade média a alta, e ainda assim com forte tradi...

Construir com alvenaria estrutural : vencer a crise com construção mais eficiente

The old municipal chambers building : damaged but nor destroyed : will it be th...

The Old Municipal Chambers is a Category I heritage building situated in Worcester Street, Christchurch. It was designed by architect Samuel Hurst Seager in the Queen Anne Arts and Crafts Style and was opened in 1887. The two storey building is constructed in solid brick and incorporates several decorative features, and it is an important part of the cultural heritage fabric of Christchurch. Some securing works...

Pushover seismic analysis of quasi-static tested confined masonry buildings thr...

The confined masonry typology has been traditionally used for building, and also selected for the reconstruction of recently earthquake-damaged cities, in developing countries responding to the seismic-economic couple. However, most of the procedures in design codes adopted for these countries are force-based, which appear to be inadequate for loading cases under severe earthquakes, where the response in displa...

Pushover analysis of a modern aggregate of masonry buildings through macro-elem...

The masonry building aggregates are a typology of construction typical of historical town centres, where a complex structural system with longitudinal and transversal walls is arranged at different ground and roof levels. Currently, the recuperation of the masonry as a structural solution will depend, in significant part, on its use in the construction of housing blocks, which can present many of the features o...

Implementação de uma solução em alvenaria estrutural de blocos de betão

A alvenaria consiste no sistema estrutural construtivo mais antigo e tem vindo a ser aplicada desde os primórdios da humanidade, verificando-se magníficas construções históricas e na arquitetura vernacular. No entanto, através dos eventos sísmicos que têm ocorrido nas mais variadas partes do mundo, tem-se verificado que a alvenaria não armada apresenta frequentemente um desempenho inadequado face à ocorrência d...

Possibilities and comparison of structural component models for the seismic ass...

This paper addresses the possibilities of structural component models for the seismic assessment of masonry buildings using pushover analysis. The ultimate goal is to allow efficient design of new unreinforced masonry buildings in seismic areas. Different modelling strategies are presented and the implementation of a simple design tool based on structural component models is described in detail. The different a...
