Week 6 Challenge

AIM: To summarize the bending moment, shear force and deflection diagrams for the elements of the model.

INTRODUCTION: while designing wheather members are suitable for the construction purpose or not can be decided based on the analyses result which include the bending moments

PROCEDURE:

• in order to obtain bending moment and shear force diagram,analyses has to be continued.
• analyses>setting>1st order analyses.
• check for modification factor for concrete and tsee.
• initially for first analyses,it should be 1.If any other values chage to 1.

• click on first order analyses,analyses will run.
• at bottom right corner,click on result view.

a.Bending moment-

• A bending moment (BM) is a measure of the bending effect that can occur when an external force is applied to a structural element.
• In tekla in result view we can find clear bending moment of each member under different loading cases and combination.
• from the obtained bending moment for major and minor,the major bending is near staircase location.

b.shear force-

• Shear force is a force acting in a direction that's parallel to a surface or cross section of a body.
• the shear force of ground floor is as per the expected,and in intermediate floor,it is more at staircase beam side.
• shear force of the column vary floor to floor.

c.deflection diagram-

• Deflection means the movement of a beam or node from its original position. It happens due to the forces and loads being applied to the body.
• Deflection also referred to as displacement, which can occur from externally applied loads or from the weight of the body structure itself.

RESULT: the bending moment, shear force and deflection diagrams for the elements of the model is studied.

AIM: Based on the analysis design the members and outline the thought process in selecting the member sizes along with the foundation design

INTRODUCTION: Structural analysis is important as it provides a basis for structural design and also it evaluates whether a specific structural design will be able to withstand external and internal stresses and forces. The structural analysis helps to determine the cause of a structural failure.

PROCEDURE:

• add seismic load to the structure using structural wizard

• analyses>setting>1st order analyses.
• check for modification factor for concrete and tsee.
• initially for first analyses,it should be 1.If any other values chage to 1.
• click on first order analyses,analyses will run.
• at bottom right corner,click on result view.
• select individual frame,select the beam first and right click.now select check selection/member.
• check if it pass all criteria,if not see the property and change the member.

• as per the loads applied,beam section varies from 300-600Mb.
• rafter beam size is Universal beam 610x305x149.
• the steel column size is 600MB.

• the concrete passed all criteria without any change.

• for slabs,design>design slab.
• review view>slab reinforcement,changed to 10 mm dia at 150mm c/c.

• for foundation modeling,foundation>paded foundation>cick on pedestarin.
• the foundation of size 2x2x0.75m size is modeled.
• similar to beam and column check the detail of foundation criteria.

RESULT: based on analysis,member are checked and resized.Also foundation is modeled.
