Retrofit for Concrete

Assessment and redesign of existing buildings .

Brief Description

The add-on “Retrofit for Concrete” contains the EN1998-1-1, Part 3 provisions and design checks for the assessment and redesign of existing buildings and for the application of reinforcement technics to existing columns and beams cross-sections.

The structure can be analyzed by applying the nonlinear static analysis method. It also includes production of the construction plans, formworks and reinforcement detailing, the bill of materials and full production of the technical report.

Analysis Methods

[infobox color=”#7bb0d8″ icon=”arrow-right”]The most reliable structural analysis method[/infobox]

  • Preliminary design performing linear static analysis method
  • Preliminary design performing response spectrum analysis method
  • Linear static analysis considering two methods based on (i) the uniform behavior factor q and (ii) the local ductility factors m
  • Nonlinear static analysis method (Pushover)
  • The most reliable structural analysis method
  • Accurate derivation of the stress resultants and the deformed shape of the structure
  • Direct localization of the “weak” regions on the structure
  • Definition of the nonlinear relation of the bending moment versus the plastic hinge rotation of each edge of the structural element
  • Analytical calculation all appropriate engineering demand parameters (stress resultants, deformations etc.) in each step of the Pushover analysis.

Seismic Design – Design Checks (EN1998-3)

[infobox color=”#7bb0d8″ icon=”arrow-right”]Drawing of the capacity curve of the structure and its equivalent bilinear curve[/infobox]

  • All the requisite seismic load combinations needed for the Pushover analysis method. Calculation of the target displacement according to the Eurocode 8, Part 3 (EN1998-3) and the Eurocode 8, Part 1, Annex B provisions.
  • Drawing of the capacity curve of the structure and its equivalent bilinear curve.
  • Check of the criteria about the adverse effect of the presence of the masonry infills on an existing structure and the automatic resistance check in each step of the Pushover analysis, according to the Eurocode 8, Part 3 (EN1998-3) provisions.
