ADJUSTMENT OF THE TELECOM COMPLEX FOR OBTAINING CPI

admin

From the survey carried out along with the original project drawings it was possible to reconstruct the current status of the fire-fighting system of the Telecom building. Although not directly observable, hypotheses have been made on the diameters and the paths of the pipes, derived from the “logic” of the original project.
From the measurements made with the pressure and flow meter it was possible to deduce the required pressure and flow rate at the point of delivery of the aqueduct to guarantee the same performances detected.
The main characteristics of the fire-fighting water network have been reconstructed with the CPIwin software.
For the identification of the elements of the network we proceeded to the numbering of the nodes and the sides of the sections.
The Hardy-Cross iterative method was used to determine the hydraulic quantities of the mesh net.
The project of the elaborate water system was necessary to verify the possibility of connecting new UNI 45 hydrants foreseen in the garage, and to propose some improvements to the existing plant that theoretically allow to meet the requirements of the UNI 10779 standard for all areas of the building.

SEISMIC VULNERABILITY

admin

The seismic vulnerability is the predisposition of a building to be damaged and collapse. The more a building is vulnerable (by type, inadequate design, poor quality of materials, construction methods and poor maintenance), the greater the consequences on the structure will be.
In technical terms, the seismic vulnerability of a structure is represented by an indicator that relates the resistance capacity of the structure and the request in terms of resistance and / or displacement of the earthquake.

The procedures for the assessment of the seismic vulnerability of buildings can be conducted with different levels of depth and complexity of calculation: from more qualitative estimates, based on the survey of the main features of the building elements, with complex numerical analysis using methods of linear and non-linear calculations.

The estimate of the seismic vulnerability index of a building follows the design process of ‘Evaluation of safety’ referred to in paragraph 8.5 of the NTC which can be summarized in the following steps.

  • Cognitive survey: the current state of construction is defined by plano-altimetric, structural surveys, and the state of damage and deformation of the structure.
  • Historical-critical analysis: it is the tool that guides the designer in the reconstruction of the current state of stress in light of the changes and events that have affected the building over time.
  • Mechanical characterization of materials: assessment of the resistance capacity of materials through surveys carried out on site or in the laboratory.
  • Definition of the levels of knowledge and of the consequent factors of confidence: we define reductive coefficients of the mechanical properties of the materials gradually smaller as the degree of in-depth investigation increases; from the level of knowledge 1 (lc1), the minimum allowed, to the level of knowledge 3 (lc3), the maximum allowed.
  • Structural analysis and determination of the vulnerability of the existing structural system;
  • Proposal for possible adjustments and evaluation of the optimal cost / benefit ratio
