Q.3)

1) Ans -

SPACE - A 3D framed structure with loads applied in any plane.this structure type is the most general.

PLANE - This structure type is bound by a global X-Y coordinate system with loads in the same plane.

TRUSS - This structure type consist of truss members which can have only axial member forces and no bending in the members.

FLOOR - A 2D or 3d structure having no horizontal movement of structure .The floor framing of a building is an ideal example of this type of structure.Columns can also be modeled with the floor in a FLOOR structure as long as structure has no horizontal loading.If there is any horizontal load,it must be analyzed as a SPACE structure.

2) Ans -

Local Coordinate System -

• Local coordinate systems define how limbs and body segments articulate about joints.
• A local coordinate system is associated with each member and is utilized in MEMBER END FORCE output or local load specification.
• Each axis of local orthogonal coordinate system is also based on the right hand rule.And this is a Rectangular system.
• A wide range of cross-sectional shapes may be specified for analysis.These include rolled steel shapes,user specified prismatic shapes etc.

Global Coordinate System -

• The Global coordinate system defines the position and translation of a body in space.
• The Global coordinate system is an arbitrary coordinate system in space which is utilized to specify the overall geometry and loading pattern of the structures.

3) Ans -

DBR stand for Design Basis Report

Basis of design report shall mean a planning report that documents the major design criteria and includes recommended project elements,planning level drawings,preliminary schedules,and cost estimates.

4) Ans -

Different types of analysis options in STADD Pro are -

• STADD building planner
• Physical modelling
• Analytical modelling
• Steel AutoDrafter
• Advanced Slab Design
• Advanced concrete Design
• STADD.Beava
• Earthquake mode

STADD building planner - STADD provides a visualization module of the building planner which generates models of the building that can be designed and analyzed in the software program.This software is interactive and intuitive which make it easy the work on making changes in the geometry specification operations with fewer mouse clicks in the workflow.

Physical modelling - Physical modelling is one of the most significant features used in the software.It is a simplified physical modelling process of a structure.This software visualize Beam,Column and surfaces placed in the model corresponding to which they appear in the physical world spanning multiple floors and a surface representing an entire floor of a building.

Analytical modelling - An analytical model can be created employing the ribbon -based user interface by making changes and editing the command file which is of types like DXF and cis/2. The model geometry can even be generated from the data of macro-enabled applications like Microsoft Excel,Micro Stations etc. by using Macros

Steel AutoDrafter - Steel AutoDrafter produces an excellent workflow plan that extracts planar drawings at any level and sections in any of the orthogonal materials from the structural steel model prepared in STADD Pro.

Advanced Slab Design - The STADD Pro Advanced slab design works within the STADD Pro environment is an integrated software design tool workflow. In this software concrete slab can be defined and the data can be passed to RAM Concept which includes all the design requirements of structural and civil design consisting of the geometry,material,loads and analysis.

Advanced concrete Design - The advanced concrete design workflow software applications powered by the RCDC application provides direct access for STADD Pro models.This software application is standalone requiring a model and result data from a suitable analysis,operating outside the STADD Pro software environment.The model is made up of beams and columns as plates are not currently supported.RCDC software application can be utilized to design the objects such as pile caps,footing,columns and walls,beams and slabs.

STADD.Beava - This design software is used in the design of bridges,consisting of loading rules and constraints,The entire process of load application is complex,as rules can impose parameters,such as loaded length on lane factors,lane and intensity of load.

Earthquake mode - In this design software,the requirement and specifications work in accordance with building structures in seismic zones and regions.These requirements ensure that the structures can sustain seismic loads and remain stable in the seismic events.The STADD Pro software workflow is used to check if the structure conforms to the basic geometric recommendations.

5) Ans -

Fixed condition -

• A fixed support is the most rigid type of support or connection.It constrains the member in all translations and rotations(i.e, it cannot moved or rotate in any direction.
• For ex, Pole and Concrete column

Fixed but support -

• The Fixed but support condition is used to allow the user to define which degree of freedom of a node are free and which are fixed.
• For ex, Pinned support is equivalent to fixed but MX,MY,MZ (no movement allowed,rotation allowed).

Practical -
