Abstract: The present invention is about a design system for the structural design of a structure or building which shall be designed following an applicable standard defining the load combinations and the control values, the said structure or building being constituted of loadbearing members and subject to loads, the load combinations defined in the said applicable standard and applied to the said loadbearing members with the substantially most unfavourable load configuration being intended to induce maximum values of stresses and/or deflections in the said loadbearing members not exceeding the control values defined in the said standard, characterized in that the said design system comprises a database intended to store the numerical values corresponding to parameters related to the act of design, the said parameters taking different numerical values depending on the structure, the building, the materials, the usage, the geographical localisation or the applicable standard.
