    Introduction to staad.pro v8i

    STAAD.Pro V8i is used to create, analyze, and design any type of virtual structure through its flexible modeling environment. The three basic activities which are to be carried out to achieve this goal are: model generation, calculations to obtain the analytical results, and result verification. All these activities are discussed individually in different chapters. STAAD.Pro is designed for engineers who understand the process of modeling, analyzing, and designing a structure.

    Basic features of staad.pro v8i

    The basic features of STAAD.Pro V8i are listed below:

    1) State-of-the art 2D/3D graphical environment.

    2) Ability to perform structural analysis and design such as static, P-delta, pushover, response spectrum, time history, cable (linear and non-linear), buckling, and steel, concrete and timber design.

    3) Ability to generate 2D/3D CAD models.

    4) Modeling of truss and beam members, plates, solids, linear and non-linear cables, and curvilinear beams.

    5) Advanced automatic load generation facilities for wind, area, floor, and moving loads.

    6) Customizable structural templates for creating a model.

    7) Toggle display of loads, supports, properties, and structural elements.

    8) User-controlled numbering scheme for structural elements.

    Starting bentley staad.pro v8i

    You can start STAAD.Pro V8i by double-clicking on the STAAD.Pro V8i icon available on the desktop. Alternatively, choose Start > All Programs > STAAD.Pro v8i > STAAD.Pro from the task bar (for Windows 7), refer to Figure 1-1; the interface will be displayed.

    User interface

    The user interface of STAAD.Pro is divided into five areas: Project Tasks, Recent Files, Help Topics, License Configuration, and STAAD News, refer to Figure 1-2. These areas are discussed next.

    Project Tasks

    The Project Tasks area contains several options which are used for creating a new project, opening an existing project, opening a STAAD model from a project wise repository, configuring settings, and so on.
