Semi-rigid design represents, by its intrinsic nature, a new option aimed at improving the competitiveness of steel construction. This objective can be achieved via Knowledge-Based approaches. In the perspective of design automation, our research proposes a novel methodology for the detailed analysis of a braced building frame adopting semi-rigid steel joints. A software tool was developed in o...

Through coming into force of the Concrete Construction Technical Regulations [1], to the European standards were also added [2] and [3] (Attachment I.4, Standards) in civil engineering, i.e. construction and geotechnical regulations. Based on this, a need appeared for revising current technical regulations [4] and critical view of new standards. A certain number of comparable analyses on as lar...

The Eurocodes provide a simplified fatigue design control through the use of Fatigue Load Model 3 (FLM3) and a damage equivalent factor, λ, which is now widely used. In applying the Eurocode method, the first problem arises when designers try to determine the corresponding fatigue span length, especially for bridge static systems not listed. A second problem is that in case of long bridges, the...

As members of Project Team SC4.T5, the authors this paper present main outcomes from work that are intended for implementation within EN 1994-1-1 (Eurocode 4). General design and application rules shallow floor beams will be presented, with a particular focus on: classification composite cross-section; non-linear bending resistance; introduction transverse bars as shear connectors.

in this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.the device has been designed on the basis of an optimization procedure with the objective tomaximize the energy dissipated in the device. the response of a 3d frame equipped with thedevice and subjected to 7...
