Following are the parameters are required in RCC Design -

1) Clear Cover - It allows you to spcify clear cover to outermost reinforement .

2) CLB and CLT - They are used to provide separate cover at top and bottom reinforcement .

3) Depth - They are used to specify limiting depth .

4) FC - Compressive strength of Concrete - This is an most imp parameters to take into consideration .

5) Fy Main - Yield Strength of steel reinforcement . - This is used to specify the yield strength of steel

6) MAX main and MAX sec = This is used to specify the diameters of bars which you are going to use.

2.2) What are the different cursor types available in STAAD Pro -

2.3) How will you generate different views for a model? State the steps involved.

i) We can create different views as per our convienent

ii) For that Select the view whichever you want

iii) Top View , Front view etc

iv) If you want to select particular element only

v) Select the element whichever you want

vi) Click on View tab

vii) Under View tab - There is an option called as Selected View only

viii) So you can see the selected view only which is helpful in Complex structres .

2.4) Explain the procedure to define a “Simply Supported” condition in STAAD Pro -

2.5) Name any five topics that you will include while creating DBR.

i) In DBR we can include following topics

1) Introduction - Which covers scope and structure of this note

2) Structural Layout - It covers brief description about structural framing system adopted for project showing plan and section of

building

3) Loads and Loads Combination - It covers brief description about loads and loads combination considered in design

4) Analysis and Design methodology - It describes the approach for structural analysis and design

5) Quality Annexure plan - It covers the quality control aspects followed in design and preparation of drawings .

2.6) Describe the term “Multi material design” of STAAD Pro.

i) After Analysis structure has to be designed to carry loads acting on it considering a certain Factor of safety

ii) In India structures are designed by using various Indian codes for both concrete and steel structures .

iii) The design in staad pro supports over 70 international codes and over 20U.S codes in 7 languages

iv) After designing the structure it is again analyzed and results of analysis for each beam and column is shown in

output file .

3)

3.1) Name the structure systems in STAAD Pro? Explain each system?

3.2) Explain the coordinate system adopted in STAAD Pro software.

i) Staad Pro uses two types of coordinate system

A) Global Coordinate System -

B) Local Coordinate System -

3.3) Elaborate DBR and its uses -

i) DBR is nothing but Daily Basis Report

ii) To specify the and compile data required for analysis and design of structural elements of the project

iii) It clearly depicts the assumptions and specification that are being used to develop the construction documents for a project

iv) It will also avoid the scop creep that can derail the project schedule and lead to budget overruns

v) It basically transform the WHAT into HOW .

vi) When a particular employee joins the new company in midway of project this DBR will help him in understanding the

project current situation

vii) All the specification and poperties , material etc all the information is akready mentioned in DBR

viii) So he need not have to go to highr authority everytime .

ix) DBR will help him in that situation

iii) As name suggests it calculate the moment with respect to apply load and calculate deformation under

apply loads

3) Perform Cable Analysis

i) This analysis is used whenever we have cable element in our model

ii) Cable analysis is generally used for Crane loading or incase of Lifting Analysis
