Romania Earth – Rediscovered Building Material
New Ways of Utilization of Old Techniques Ecology is currently an everyday topic, and the building sector is one of the most energy and resource consuming field. The outline of the characteristics a building material should fulfil in order to be ecological is focused on one of the oldest construction techniques, the use of local earth. A review of the variety of contemporary usages is followed by reflexions on today’s oblivion of this material in the Banat region, where it has a centuries old tradition.

Motorization development and new challenges at rapidly developing European countries
The rapid motorization in new EU countries, which started at the beginning of 1990’s has bring the new situation in urban planning and mobility engineering of these countries, which is characterized with congestion, worsening environmental situation, increased number of road collisions, but also causing a number of new phenomena like urban sprawl and changing travel habits. This paper describes the background of this development as well as a new role of technical expertise in order to face this situation and propose new innovative solutions.

Influence of Concrete Confinement and Degree of Shear Connection on the Behaviour of Hybrid Columns
This paper investigate the influence of concrete confinement and degree of shear connection effects on the ultimate load of hybrid steel-concrete columns with several encased steel profiles. Primarily, a co-rotational finite element for large displacement analyses of hybrid beam-columns in partial interaction and with shear deformability of concrete component is developed. In local co-rotational coordinate system, a fiber model considering the triaxial stress state in the concrete component is adopted. This consideration enables to take into account the contribution of the transverse reinforcement on concrete confinement by using the extended plane stress algorithm, in which the transversal equilibrium between the concrete fiber and the transverse reinforcing bar is enforced. The performance of the FE model is illustrated by comparing its prediction against experimental three-point flexural bending tests of hybrid beams. The results of parametric study using the FE model show that for low to high column slenderness, the ultimate load of hybrid column increases significantly with respect to the transverse reinforcement ratio. Besides, the ultimate load of slender columns in full interaction can be obtained for columns with a relatively high shear connection stiffness at the extremities without shear connection along the column height.

Seismic Risk in Romania. Assessment and Awareness
Earthquakes poses the risk with the highest impact in Romania. The presentation focuses on the seismicity of Romania, the exposure of the building stock, the fragility of reinforced concrete buildings and the earthquake risk assessment of residential buildings, with an emphasis on Bucharest. Moreover, based on the results of a recent survey, the level of seismic awareness of Bucharest population is discussed and the main findings are highlighted.

Mola: A New Way to Study and Teach Structural Behavior
Mola is a physical model, composed of a set of modular parts that are connected through magnetism allowing countless combinations. Users can build, visualize and feel the structures using their own hands. It is a hands-on activity that can help people to understand abstract concepts in a tangible and concrete manner. In this illustrated lecture, the Brazilian architect Marcio S. Oliveira shares an overview of his remarkable project – Mola Structural Model. He will also talk about the stories behind the project, from the initial idea to design development, scientific validation, fundraising and his plans for the future of Mola.
