This study focus on derivation of such vulnerability curves using Fiber Reinforced Polymers technologies retrofitted conventional RC industrial frames with masonry infill wall. A set of stochastic earthquake waves which compatible with the response spectrum of China seismic code are created. Dynamic time history analysis is used to compute the random sample of structures. Stochastic damage scatter diagrams based different seismic intensity index are obtained. Seismic vulnerability of FRP-reinforced RC industrial frames is lower than unreinforced frames obviously, and seismic capability of frames using FRP technologies is enhanced especially under major earthquake.

In this chapter, a numerical study to investigate the seismic vulnerability of the two storey colonnade of the Forum in Pompeii has been conducted. Software based on the Distinct Element Method (DEM) of analysis has been used. The colonnade was represented as an assemblage of distinct blocks connected together by zero thickness interfaces which could open and/or close depending on the magnitude and direction of stresses applied to them. Both static and non-linear static analyses have been undertaken. Also, a sensitivity study has been performed to investigate the effect of frictional resistance of the joints on the structural response of the colonnade. This was to simulate potential joint degradation effects and/or possible water lubrication at the joint.

Industry plays a key role in the economy of a country, people welfare and socio-economic resilience to natural disasters. Earthquakes are known to have damaging impacts on industrial property and activity, oftentimes resulting in costly structural and non-structural losses to industrial buildings, business closure, production failure and job losses. Notwithstanding this fact, the industrial building stock has been continuously excluded from seismic risk models developed for Portugal as it is usually assumed that industrial buildings are expected to withstand strong earthquakes due to their lightweight and design governed by wind loads. The aim of this paper is thus to give a first contribution to the assessment of the seismic vulnerability and property losses of the existing Portuguese industrial steel building stock. Both losses to structural and non-structural components and industry-specific contents, such as production equipment and machinery, are taken into account. The expected direct industrial property losses for a probability of exceedance of 10 % in 50 years for mainland Portugal are herein estimated.

Background:Recent major earthquakes in the centre of the Italy, between August and October 2016, have reaffirmed the seismic vulnerability of precast industrial buildings with a lot of collapse recorded. This is typical due to the past Italian building practices, where structural deficiencies are mainly related to the capacity to transfer horizontal forces between primary structural elements.Objectives and Methods:In these types of structures, a key role is played by the dowel pin connections which allow to transfer lateral horizontal forces from the beam to the column, without losing load carrying capacity. For this reason, in this work, the assessment of the seismic fragility of single-story reinforced concrete precast building located not far from the epicentres of the two aforementioned earthquakes was done.Results and Conclusion:The seismic risk was evaluated in terms of annual frequency of exceedance for three performance levels provided by the European and Italian seismic codes, considering the mean hazard curves for the site. The comparison between the fragility of different structural models shows the importance in the choice of the column-beam connection modelling to obtain reliable results on the structural safety assessment.

An innovative dissipative (INERD Pin) connection system, which was previously developed for seismic resistant X-braced steel frames, was applied to retrofit existing precast industrial buildings designed only for gravity loads. Nonlinear dynamic analyses were carried out and the effectiveness of the dissipative connection system was evaluated. The INERD Pin connection system increased both the deformation capacity and the stiffness of the buildings, reducing damage of the structural elements. In case of low seismic actions, the INERD Pin connection system especially enhanced the stiffness of the structure, causing only small reductions of column rotations and top displacements. In case of severe seismic actions, the addition of the dissipative connections showed all its effectiveness particularly for low rotation capacity at column base, increasing the energy dissipation capacity and reducing the displacements of the structure. The results of the numerical investigations demonstrated the possibility to reduce the seismic vulnerability of existing precast buildings by means of dissipative connection systems.
