A simple calculation method is proposed for predicting the elastic and plastic behavior of moment resistance timber frames without using non-linear numerical analyses by wire frame modelling. The which have multiple stories spans can be calculated hand or spreadsheets based on flexural stiffness members spring behaviors joints. accuracy been verified comparing results with experiments under sev...

Seismic vulnerability of reinforced concrete (RC) buildings is strongly influenced by beam-column joints. Horizontal and vertical structural members converge in joints, as extremely delimited areas where the internal forces core reinforcing bars have elevated stress gradients. In order to fully understand seismic behavior RC related failures T- X-shaped joints (external corner internal-position...

The study presented in this paper analyses and investigates the possibility of introducing a general rapid methodology based on an artificial neural network (ANN) to assess seismic response existing reinforced concrete (RC) buildings. Starting from investigations carried out buildings located outskirts Bologna, 928 finite element models have been developed basis most recurrent data. input param...

Building structures are subject to displacement under the influence of forces resulting from earthquake. The most common method of controlling such displacements in steel structures, which are usually of lateral type, is the use of braces. Depending on designing requirements and feasibility, braces are available in various forms. Configuration of bracing systems is generally of concentric or ec...

We examine the thermal fluctuations of the local electric field Ek (loc) and the dipole moment μk in liquid water at T = 298 K between metal walls in electric field applied in the perpendicular direction. We use analytic theory and molecular dynamics simulation. In this situation, there is a global electrostatic coupling between the surface charges on the walls and the polarization in the bulk....
