    Abstract

    Scia Engineer software enables the user to design and check 2D member reinforcement. Themain possibilities of the design and checks are presented in the table below.

    Steps of design and checks for 2D members Concrete tree for 2D members

    The aim of this document is to describe each step of the design and check of a 2D member andto describe some of the tips and tricks which might be important and useful in each part.

    2 Global settings

    Global settings represent a set of parameters which are default values for the design of thewhole structure in the project. The user can use these default values, change them or simply createhis own sets of parameters reflecting his preferences and needs. General settings can be accessed inseveral ways:

    o Project data

    o Manager of National annexes

    o Setup manager

    o Concrete solver

    o Design defaultsin Concrete tree

    o By pressing action button Concrete setupin Concrete tree > Member design

    2.1 Project data

    The first possibility to change the global settings of the project is through the project dialog. Youc
