1. Numerical formulation for nonlinear analysis of concrete and steel shells with deformable connections
Abstract A two-dimensional interface finite element capable of associating flat shell elements positioned one above the other was developed. The implemented interface element can physically simulate the contact between the flat shell elements and connect the reference planes of the shell elements above and below it. The formulation presented allows considera

2. Analytical study of cylindrical tanks including soil-structure interaction
Resumo Um estudo analítico voltado para o projeto de tanques cilíndricos para armazenagem de líquidos, apoiados sobre fundação deformável, é desenvolvido neste trabalho. O solo sob os tanques é modelado como um meio elástico linear. A parede cilídrica é considerada rigidamente conectada à placa de fundação. Aqui, tanques de concreto são enfati

3. Static and dynamic analysis of reinforced concrete shells
The objective of this work is to provide a reliable numerical model using the finite element method (FEM) for the static and dynamic analysis of reinforced concrete (RC) shells. For this purpose two independently computer programs based on plasticity and viscoplasticity theories are developed. The well known degenerated shell element is used for the static a

4. Propagação de ondas de ultra-som em prototipos de postes tubulares de concreto armado / Propagation of waves ultrasound in prototypes of reinforced of concrete tubular poles
Os postes de concreto apresentam, para os diferentes fabricantes, grande variabilidade em termos de qualidade e resistência inicial. Essas diferenças, provenientes de problemas durante a fabricação, têm se refletido na vida útil dos postes instalados na rede de distribuição de energia. Para ser aceito como fornecedor de poste de uma determinada conce

5. Resistência e deformabilidade de blocos vazados de concreto, prismas e paredes e suas correlações com as propriedades mecânicas dos materiais constituintes / Strength and deformability of hollow concrete blocks, prisms and walls and their correlation to mechanical properties of constituent materials
This work aims to identify and correlate the mechanical properties of concrete and bedding mortar to the structural behavior of hollow concrete blocks, prisms and walls, by mean of physical and numerical modeling. A detailed experimental investigation was carried out by assuming as a premise the use of plastic consistency concrete to produce hollow blocks an

6. Proposed mechanism for stability of proteins to evolutionary mutations
It is shown that the sequence-ordering tendencies induced by design into different fast-folding, thermally stable native structures interfere. This interference results in a type of quasiorthogonality between optimal native structures, which divides sequence space into fast-folding, thermally stable families surrounded by slow-folding, low stability shells.
