Special Issue Information

Dear Colleagues,

The development of smart cities cannot be separated from the development of their infrastructures. To have a balance between sustainability and optimal structures, designers need to investigate the impact of new unconventional materials or common materials used for new construction systems on the structure reliability. As, for example, in the field of bridge engineering, the structural design follows consolidated laws to estimate the structural stability under traffic or wind loads, based on literature or guidelines in codes of practice. However, for designers to use new materials or new construction systems, guidelines must be updated. Similarly, road covering, tunnels, dikes, and other crucial infrastructures need to be built faster using new materials or new techniques. The mass distribution, the structural damping, the fatigue phenomenon, flutter phenomenon, and other important issues depend on material mechanical characteristics or constructional technology. These closely affect the structural reliability that should be investigated carefully through experiments or numerical analyses to achieve prototyping. Generally, the prototyping process is focused on case studies to achieve a generalization. Some examples can be new construction technology through wood systems or recycling materials. We expect that these materials achieve the same safety as traditional materials, such as, for example, reinforced concrete or steel. However, to achieve these goals, structures should be designed differently, using non-traditional materials. Of course, in the first phase of an investigation, results will not necessarily be all positive or solutions will not the best, but are, regardless, interesting for designers. This Special Issue will collect several case studies of infrastructures designed using new materials or new constructional systems. The Special Issue should be interesting for both designers and companies to develop research projects.

The work described in this paper investigated, by calculating critical flutter speed, the aeroelastic response of suspended pedestrian bridges made of a laminated wood structure and hemp cables and compared them to bridges with a steel structure and harmonic steel cables. Critical flutter speed was estimated using a numerical two degree of freedom (2-DOF) generalized deck model based on finite-element modal analysis. The critical flutter speeds of two sets of 25 different structural configurations, obtained by varying the deck chord and the permanent deck loads, made of steel and of laminated wood respectively, were estimated using experimental flutter derivatives obtained from 30 wind tunnel experiments. One of the most significant results was that pedestrian bridges made of laminated wood and hemp have a higher torsional frequency than those made of steel and that this affects critical flutter speed. A case study was performed and discussed by analyzing the structural and aeroelastic response of a 250 m pedestrian bridge with a 12 m deck chord and two approximately 32 m tall towers. Full article
