1 Choose the right model type

STAAD can handle different types of models, such as beam, plate, solid, cable, and truss. Depending on your structure and design objectives, you should choose the most suitable model type that can capture the relevant behavior and loading conditions. For example, if you are designing a steel frame, you can use a beam model with appropriate section properties and connections. If you are designing a concrete slab, you can use a plate model with appropriate thickness and material properties. Choosing the right model type can reduce the complexity and size of your analysis, and improve the accuracy and speed of your results.

Optimizing the performance of STAAD in structures is affected by several factors: 1- Think about the nature of your structure and what's the best model for it. 2- Tailor your model for each project/structure. 3- Define your materials. 4- Add all affecting loads and forces. 5- Reflect on the soil report and the geographical location.

Selecting the appropriate model type in STAAD is critical for accurate structural analysis. Tailor your choice to the specific characteristics and loading conditions of your structure. Opt for a beam model for steel frames, incorporating suitable section properties. For concrete slabs, a plate model with the right thickness and material properties is apt. This strategic model selection not only streamlines analysis but also enhances result accuracy and efficiency.

2 Simplify your geometry and mesh

STAAD allows you to create and modify your geometry and mesh using various tools and commands. However, you should avoid creating unnecessary or excessive elements that can increase the computational cost and time of your analysis. For example, you can use symmetry or repetition to simplify your geometry and mesh, and reduce the number of nodes and elements. You can also use coarse or fine meshing options to control the level of detail and refinement of your elements, depending on the critical areas and load cases of your structure. Simplifying your geometry and mesh can enhance the efficiency and stability of your analysis, and avoid errors and warnings.

In STAAD, optimizing geometry and mesh is vital for efficient analysis. Utilize tools judiciously, avoiding unnecessary elements that can inflate computational costs. Leverage symmetry or repetition to streamline geometry, reducing nodes and elements. Tailor meshing options for coarse or fine detailing based on critical areas and load cases. This simplification not only enhances analysis efficiency but also ensures stability, minimizing errors and warnings.

3 Use appropriate load cases and combinations

STAAD enables you to apply different types of loads and load cases to your structure, such as dead, live, wind, seismic, temperature, and so on. You can also create load combinations using various factors and methods, such as linear, envelope, absolute, or SRSS. However, you should use only the necessary and relevant load cases and combinations for your structure and design criteria. For example, you can use load factors and load combinations from the applicable codes and standards for your structure and location. You can also use load envelopes or load lists to group and select the most critical load cases and combinations for your design. Using appropriate load cases and combinations can optimize the load application and design output of your analysis, and avoid redundant or unrealistic scenarios.

In STAAD, precision in load application is key. Apply only necessary load cases—dead, live, wind, seismic—relevant to your structure and design criteria. Craft load combinations judiciously using factors and methods aligned with applicable codes and standards. Leverage load envelopes or lists to identify critical cases for design. This precision ensures optimal load application, streamlining analysis outcomes and steering clear of redundant or unrealistic scenarios.

4 Check your results and reports

STAAD provides you with various options to check and verify your results and reports, such as graphical displays, tables, charts, diagrams, and text files. You can use these options to review and evaluate your analysis results, such as displacements, forces, stresses, moments, reactions, and so on. You can also use these options to generate and customize your design reports, such as summary, details, bill of materials, drawings, and so on. However, you should check your results and reports carefully and critically, and compare them with your expectations and assumptions. For example, you can check for any errors or warnings in your analysis or design, and identify the possible causes and solutions. You can also check for any anomalies or discrepancies in your results or reports, and validate them with other sources or methods. Checking your results and reports can ensure the quality and reliability of your analysis and design, and help you improve your performance and skills.

5 Update and upgrade your software and hardware

STAAD is constantly updated and upgraded by its developers and users, to incorporate new features, enhancements, bug fixes, and user feedback. You should keep your software and hardware updated and upgraded, to take advantage of the latest improvements and innovations in STAAD. For example, you can download and install the latest patches and versions of STAAD from the official website or online platform. You can also upgrade your hardware and system requirements, such as memory, processor, graphics card, and operating system, to support the optimal performance of STAAD. Updating and upgrading your software and hardware can increase the functionality and compatibility of STAAD, and boost your productivity and efficiency.
