25. Step by Step Sample Project • Here we are going to take a quick look at the steps required to go through to create a SazehNegar project, design different kinds of connections and finally create the structural drawings and reports.

26. Step1: Making Mdb files in SAP2000 or ETABS • When the analysis and design is finalized in ETABS or SAP2000 we should make the Mdb files needed in SazehNegar.

27. Step 2: Importing Mdb file • In SazehNegar we should import the Mdb file created in the step 1. • SazehNegar will check if all the data is correctly inserted in the Mdb file.

28. Step 3. Mapping the profiles • In this step we should map the profiles existing in Mdb files to new profiles in SazehNegarby means of section designer. • Linear elements • Wall and deck sections • SazehNegar can retrieve the sections defined using ETABS section designer by means of e2k file.

30. Step 4. Finalizing Import • In this step user can enter the project information such as address, title, owner, structure designer and … • The last thing to check is load case properties. SazehNegar will show the list of load cases retrieved from Mdb and user can add/remove selected ones.

32. Step 5. User Interface • Standard dual window display • Real profiles display • Elements color customization • Changing beams alignment • Main menu and toolbar

34. Step 6. Beam to column connections • Here user may take advantage of any of following tools: • Auto Connection tool: detects and sorts all the existing beam-columns joints in the project. • Single joint connection design: user manually selects the joint and goes through design and assignment process or he may design a connection using user-defined loads independent from the project joints.

36. SazehNegar checks every single user modification to connection and logs the conflicts and warnings below the 3d view. The design will be final when all the connection parts become green and warning messages are disappeared.

38. Step 7. Bracing gusset plates • Both automatic and manual design are available. • The general procedure is almost the same as beam to column connection design. • User may design new connections, modify existing connections or remove assignment and delete the connections.

39. Filtering options List of all bracing connections

40. Step 8. Design results check • Now that all beam to column connections and gusset plates are designed, user may ask SazehNegar to check all the connections individually against their own real positions and configuration. • SazehNegar reports the probable problems at the bottom of the main window below main views. • User may click on each line of the report to zoom into the selected connection and examine the problem more closely.

42. Step 9. Base plates • Filtering and sorting is automatically done using the columns profile. • User may enter eccentricity for each base plate individually. • The precise amount of stress is calculated for all the four corners of base plate using biaxial stress calculation. • Tension in each anchor bolt is precisely measured.

44. Step 10. Drawings and Material Lists • User may change all the colors, layers, fonts, text styles and scales used in drawings. • Options for creating different types of drawings are categorized in separate sections in Settings windows. • User may choose to create all the drawings in one single phase or create drawings of specific type. • User can plot the drawings directly from SazehNegar. • User may edit the drawings using the Drawing Editor before exporting or plotting the drawings.
