1. Estudo experimental do fluxo de umidade em argamassas de cal aérea
RESUMO Uma parte significativa do património histórico construído ao redor do mundo é constituída de alvenaria estrutural, com juntas preenchidas com argamassa. Nesses sistemas estruturais, a argamassa usualmente representa uma parcela pequena/moderada do volume total da estrutura, no entanto, a argamassa é reconhecida como a principal fonte de movimen

2. Comparison of Developed Numerical Macro and Micro Masonry Models for Static and Dynamic Analysis of Masonry-infilled Steel Frames
Abstract First, the basic characteristics of macro and micro masonry models in numerical analyses of masonry structures are discussed. Afterwards, developed numerical macro and micro masonry models, intended for the nonlinear static and dynamic analysis of unreinforced and confined masonry walls, as well as of masonry-infilled frames, are briefly presented.

3. Estudos e propriedades mecânicas de um novo tipo de bloco cerâmico híbrido para edificações em alvenarias estruturais
This dissertation presents a hybrid ceramic block the use of which reside in the buildings executed with walls. Initially, we conducted a survey on the requirements and / or norms prevailing in Brazil about structural ceramic blocks, making use of the experiences in other countries. This work seeks new materials and / or products in order to maintain or incr

4. Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
Models based on the continuous damage theory present good responses in representing the nonlinear behavior of reinforced concrete structures with loss of strength and stiffness of the material. However, damage theory is rarely employed in the analysis of masonry structures and numerical simulations are currently performed mostly by Finite Element Method form

5. Finite element nonlinear analysis of high-rise unreinforced masonry building
A simple efficient algorithm based on compressive diagonal strength of unreinforced masonry walls is presented to determine capacity curve of unreinforced masonry building. The compressive strength is calculated based on a new close form solution. The new close form solution is determined based on predicted results using interface elements for modeling of mo

6. Análise experimental e numérica do comportamento de junta em painéis de contraventamento de alvenaria estrutural / Experimental and numerical analysis of the joint behavior of masonry shear wall
A avaliação da capacidade de carga das estruturas de alvenaria submetidas a ações horizontais depende da confiabilidade dos modelos de dimensionamento utilizados. De fato, a alvenaria é um material heterogêneo com característica ortotrópicas. Além disso, por possuir juntas de argamassa que acarretam planos de fraqueza, geralmente a modelagem computa

7. Lateral strength force of URM structures based on a constitutive model for interface element
This paper presents the numerical implementation of a new proposed interface model for modeling the behavior of mortar joints in masonry walls. Its theoretical framework is fully based on the plasticity theory. The Von Mises criterion is used to simulate the behavior of brick and stone units. The interface laws for contact elements are formulated to simulate

8. Interfaces físicas entre os sistemas prediais hidráulicos e sanitários (SPHS), estruturais e vedações / Physical interfaces among plumbing, cast in-situ reinforced concrete and mansory systems
The identification and resolution of interfaces is a requirement that must be met for additional methods for evaluating design for Hydraulic and Sanitary Building Services (plumbing systems). The reason is that these building systems, in general, may have a higher incidence of problems of compatibility with others, because they all relate to. In this context

9. Experimental small-scale analysis of the connections between structural clay block work masonry walls submitted to vertical loads / Análise experimental em escala reduzida de ligações entre paredes de alvenaria estrutural de blocos cerâmicos submetidas a ações verticais
This work presents a comparative analysis of three types of connections between structural masonry walls under vertical loads. The first type is a set of running bond interconnected masonry walls. The second connection is obtained by means of steel meshes and the third, also stack bond, is hardened by metallic staples anchored in grouted holes. The study is

10. Estudo de painéis de alvenaria estrutural sujeitos a ações perpendiculares ao plano
There are several cases of out-of-plane loaded masonry such as earth retaining walls, water reservoir, wind loaded panels and other. Thus, there is a lack of Brazilian technical literature in this topic. The aim of this thesis is to fulfill this lack and to be as a reference text to design such structures. The litterature review covers recommendations from s

11. Sobre o dimensionamento do revestimento contra fogo de estruturas de aço. / Determination of the fire protective material in steel structures.
This present work shows some methodologies to determine the thickness of the fire protective material in steel structures in a fire situation. It shows analytical methods based on actual standards and results of experimental analysis by international and national laboratories. The application of the program Super Temp Calc (STC) is detailed, by thermal analy

12. Influência da alvenaria no comportamento estrutural de edifícios altos de concreto armado / Influence of masonry infill panels on the structural behavior of tall reinforced concrete buildings
Apresenta-se neste trabalho a análise numérica de um edifício de 32 pavimentos, em concreto armado, situado na cidade do Recife. Primeiramente foi realizada a modelagem pelo método dos elementos finitos apenas para a estrutura em concreto. Em seguida realizou-se a modelagem considerando o efeito dos painéis de alvenaria de vedação no comportamento est
