Numerical modelling of masonry-infilled reinforced concrete frames : model cali...

Akhoundi, Farhad; Lourenço, Paulo B.; Vasconcelos, Graça

Generally two methods are proposed for analyzing the infilled frames; Micro modelling approach which finite element method is used to take into account local effects in detail and Macro modelling approach which is a very simplified method that takes into account the global behavior of the structure by replacing the infill with diagonal strut. In the present study a numerical analysis is carried out on a one bay...

Experimental assessment of an innovative strengthening material for brick mason...

Martins, Andreia Piedade Gomes; Vasconcelos, Graça; Fangueiro, Raúl; Cunha, Fernando Eduardo Macedo

The vulnerability of masonry infill walls has been highlighted in recent earthquakes in which severe inplane damage and out-of-plane collapse developed, justifying the investment in the proposal of strengthening solutions aiming to improve the seismic performance of these construction elements. Therefore, this work presents an innovative strengthening solution to be applied in masonry infill walls, in order to ...

Paredes de alvenaria de enchimento e a ação sísmica: reabilitação e inovação

Vasconcelos, Graça; Akhoundi, Farhad; Lourenço, Paulo B.; Silva, Luís, M.; Martins, Andreia Piedade Gomes

Neste trabalho apresentam-se os principais resultados da investigação efetuada na Universidade do Minho relacionada com a análise do comportamento de paredes de enchimento sujeita a ações sísmicas e metodologias de reforço com a proposta de um novo material desenvolvido na perspetiva de reabilitação destas paredes construídas em regiões sísmicas. Apresentam-se também algumas possibilidades para construção nova ...

In-plane and out-of plane experimental characterization of rc masonry infilled ...

Akhound, Farhad; Vasconcelos, Graça; Lourenço, Paulo B.; Palha, Carlos Alberto Oliveira Fernandes; Silva, Luís C.

Seismic investigations of typical south European masonry infilled frames were performed by testing two reduced scale specimens: one in the in-plane direction and another in the out-ofplane direction. Information about geometry and reinforcement scheme of those structures constructed in 1980s were obtained by [1]. The specimen to be tested in the in-plane direction was constructed as double leaf masonry while th...

Out-of-plane behavior of masonry infill walls

Akhoundi, Farhad; Vasconcelos, Graça; Lourenço, Paulo B.; Palha, Carlos Alberto Oliveira Fernandes; Martins, Andreia

In order to investigate the out-of-plane behaviour of masonry infill walls, quasi-static testing was performed on a masonry infill walls built inside a reinforced concrete frame by means of an airbag system to apply the uniform out-of-plane load to each component of the infill. The main advantage of this testing setup is that the out-of-plane loading can be applied more uniformly in the walls, contrarily to poi...

Doctoral Thesis Civil Engineering; A vulnerabilidade sísmica de edifícios de betão armado preenchidos com paredes de alvenaria tem vindo a ser constatada durante sismos recentes no sul da Europa, causando um número elevado de mortos e elevados custos de reabilitação ou reconstrução, e justifica a necessidade de estudos detalhados acerca do comportamento sísmico de pórticos de betão armado preenchidos com alvena...

Akhoundi, F.; Lourenço, Paulo B.; Vasconcelos, Graça

Aimed at investigating the effect of openings on the in-plane behaviour of masonry infills in reinforced concrete frames, a parametric study is presented based on model calibration via experimental tests. Two types of openings are investigated: central window openings and different combinations of door and window openings based on the typologies of southern European countries. First, a finite element model of t...
