First lecture:
Gonçalo Castro Henriques
In this presentation Gonçalo Castro Henriques will share his recent experience at the the federal university of Rio de Janeiro. The presentation will present «LAMO - Laboratório de Modelos 3d e fabricação digital» (laboratory of 3d models and digital fabrication) and a brief resume of the lab history, approach and future goals in Latin America context. 

LAMO is a young lab, developing a collaboration network with other laboratories and research centers. the presentation will highlight the contribution of 3 projects:  «wiki-house/casa revista (2015)» and the international workshops «sensitive shelters/ abrigos sensíveis (2014)», and «defying gravity/desafiando a gravidade (2015)».

Second Lecture: 
Juarez Franco 
This work presents an application of Shape Grammar (SG) in automatic design of spatial trusses (ST) manufactured with tubular steel members.
SG is a powerful approach for geometric parameterization based on set of rules and recursive application over an initial shape.
This strategy offers control over a large domain of topologies from a relatively short set of parameters, which may control the main geometrical properties of the system. These characteristics (large domain, few parameters and efficient constraint) have a very important influence over the computational costs and results in usual optimization algorithms, as for example the topological optimization by Genetic Algorithms. In this context, Shape Grammar proved to be an efficient approach for improvement of structural steel products [1].
The main contributions of the present work are developments and implementation of parametric rules for a specific ST-Grammar.
A graphic user interface is provided taking advantage of OpenGL. All algorithms are implemented in a mixed Fortran/C++ language. Finally, illustrative examples of spatial trussed roof systems are shown.
