    2. Run the analysis. Summarize your understanding of the analysis results

AIM:- To run the analysis and to summarize the analysis results

INTRODUCTION:- Analyical diagrams like Bending moment, Shear force, Axial force and deflection are used for the study of behaviour of each member of the building.

PROCEDURE:-

• Go to analyse, under settings check modification factor for concrete as 1.

• Run under 1st order analysis. Select all load combinatons.

• After run analysis, the status shows no error.
• Expand the overall displacement, check the maximum positive displacement for both strength and service in solver view.
• Highlight the node for displacement along z axis to check maximum displacement for the member as shown 

• In results view, under results select deflections for different load combinations. Therefore, maximum deflection is shown in load combination 3

  DEFLECTION DUE TO GRAVITY ON THE STRUCTURE

• Select the frame 3 from project window, to check the deflection diagram.

   DEFLECTION DUE TO GRAVITY

• The deflection due to gravity in picture above is correct.
• But the deflection at the cantilever ends are high.
• Similarly, check for different load combinations
• Deflection due to wind is shown below.

 

Axial force

• In result view, select Axial force from results tab.
• Maximum axial force for column is shown for load combinations 3.

• Select the frame 3 from project window, to check the axial force diagram.
• The axial force is acting maximum at bottom of the column which is correct.
• Similarly, check for different load combinations

   AXIAL FORCE FOR GRAVITY LOAD

    MAXIMUM AXIAL FORCE FOR LOAD COMBINATION 3

Bending Moment

• For frame 3, select moment major from results tab.

  MAXIMUM BENDING MOMENT IS SHOWN IN LOAD COMBINATION 3

• Bending moment at the end of the cantilever beam is 0 which is correct. 
• Similarly, check for diffenent load conditions such as wind and seismic.

   BENDING MOMENT FOR WIND LOAD CONDITION

   MAXIMUM BENDING MOMENT ON THE STRUCTURE FOR LOAD COMBINATION 3

Shear force

• For frame 3, select shear major from results tab.
• Check shear major for different load conditions and combinations.

  MAXIMUM SHEAR FORCE IN LOAD COMBINATION 3

   SHEAR FORCE FOR WIND LOAD CONDITION

  SHEAR FORCE FOR SEISMIC LOAD COMBINATION

 RESULT:- Hence, summarized the analysis results obtained after run analysis.
