Introduction In Tekla Structures, we use the term parts to refer to the basic components of a model. These are the building blocks of the physical model. For structural analysis purposes, we use the term members to mean load-bearing parts. The main concrete parts are: • beam • polybeam • column • pad footing • strip footing • panel • slab The main steel parts are: • beam • curved beam • orthogonal beam • polybeam • column • twin profile • contour plate |

In this chapter |
This chapter explains how to create and modify parts using different materials and profiles. It |
||
also includes a general description of part properties and an overview of part commands. You can find step-by-step instructions for all these commands in the online help. We assume that you have read Chapter 1, or have comparable knowledge of Tekla Structures. Before you start to create parts, you need to create grids, views, and points, as explained in Chapter 2, This chapter is divided into the following sections: |

Finish Finish is user-definable. It describes how the part surface has been treated, e.g. with anti- corrosive paint, hot galvanized, fire retardant coating, etc. Class Use Class to group parts. To display parts of different classes in different colors, click View > Representation > Object Representation… and select Color by class in the Color list box. Tekla Structures contains standard, parametric, and user-defined profiles. Standard profiles When you first start Tekla Structures, the profile catalog contains standard, environment-specific profiles. The properties of these library profiles conform to industry standards, so you should not edit them. You can add profiles to the profile catalog. See The profile catalog in the online help. Parametric Parametric profiles are partly user-definable, they have a predefined shape, but you determine profiles their size by giving one or more parameters. You can use parametric profiles to closely “model” profiles that are standard in specific environments, but do not exist in the Tekla Structures profile catalog. Parametric profile names have specific prefixes and include dimension values. These are described in Appendix A, Parametric Profiles If you want to define alternative prefixes for parametric profiles, see Customizing parametric profiles in the online help. Dimension values in parametric profile names are separated by standard separators -, X, /, or *. If you want to define additional separators, see XS_PARAMETRIC_PROFILE_SEPARATOR and XS_USER_DEFINED_PARAMETRIC_PROFILE_SEPARATORS in the online help. User-defined You can also create your own profiles and save them in the profile catalog. For example, you profiles could create a user-defined profile pitched, with different cross sections at the beginning and end of the profile. You can also define cross sections. To create user-defined cross sections, you pick the points which define the cross section corners. To create your own profiles, see Sketching and using cross sections To select the profile of a part, click Select… next to the Profile field in the part properties dialog box. The Select Profile dialog box appears. |

All profiles and details | You can select a profile from the tree which lists profiles contained in the profile catalog. Profiles are grouped in the tree according to rules (such as profile type) which you can define and modify. Only the profile types that are relevant to the material of the part are shown. For more information on how to modify the profile catalog and rules, and how to associate profile types with materials, see The profile catalog and Working with rules in the online help. If you select a parametric profile, enter the profile dimensions in the Value column. If you select the Show all profiles checkbox, Tekla Structures includes all the profiles in the profile catalog in the tree. To see all the properties of profiles, select the Show details checkbox. For user-defined profiles Tekla Structures also displays cross section information. When you have selected a profile, click Apply or OK. |

Aliases and To include aliases for material grades in the tree, in the Select material dialog box, select the details Show aliases checkbox. Aliases are alternative names. For example, they can be former names, or names used in different countries or standards. Tekla Structures automatically translates aliases into the standard name when you select a material grade. To see all the properties of materials, select the Show details checkbox. |

Analysis The Analysis tab contains information on the properties used in structural analysis, including the modulus of elasticity, Poisson's ratio, and thermal dilatation coefficient. design The Design tab contains information on design-specific properties, such as strengths, partial safety factors, etc. User attributes Use the User attributes tab to view or modify the user-defined properties of materials. For example, this tab could contain the maximum grain size, porosity, or surface quality class of a concrete material type, or country-specific properties. When you have selected the material for a part, click Apply or OK. |
