Q3]

AIM: -

1. Name the structure systems in STAAD Pro? Explain each system?

2. Explain the coordinate system adopted in STAAD Pro software.

3. Elaborate DBR and its uses

4. Explain the different types of analysis options in STAAD pro.

5. Explain the difference between Fixed and Fixed But condition.

PROCEDURE: -

(i)

A structure can be defined as an assemblage of elements.

STAAD.Pro is capable of analyzing and designing structures consisting of frame, plate/shell, and solid elements.

a) SPACE

A3D framed structure with loads applied in any plane. This structure type is the most general.

b) PLANE

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

c) TRUSS

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

d) FLOOR

A 2D or 3D structure having no horizontal movement of the structure.

The floor framing of a building is an ideal example of a this type of structure.

Columns can also be modeled with the floor in a Floor structure as long as the structure has no horizontal loading.

If there is any horizontal load, it must be analyzed as a Space structure.

(ii)

Co-ordinate Systems

a) Global Co-ordinate System

This coordinate system is a rectangular coordinate system (X, Y, Z) which follows the orthogonal "right hand" rule.

This coordinate system may be used to define the joint locations and loading directions.

The translational degrees of freedom are denoted by u1, u2, & u3 and the rotational degrees of freedom are denoted by u4, u5, & u6.

b) Local Co-ordinate System

Each member or surface has its own local Cartesian coordinate system which is also oriented using the "right hand" rule.

The longitudinal axis of a member is the first axis, with the positive axis taken from the i to the j ends (i.e, Ni and Nj).

The second axis is the oriented such that the 1-2 plane is then parallel to the global Y axis.

The third axis is then normal to the first and second local axes as defined by the right hand rule.

The local 2 and 3 axes coincide with the two principle moments of inertia of the cross-section.

In the special case of a vertical member (where the local 1 axis is parallel to the global Y axis; i.e., a column), the local 3 axis is then made parallel to the global Z axis and the 2 axis is oriented respectively.

(iii)

DBR

The purpose of this document is to compile data required for analysis, design and detailing of all structural steel and RCC elements viz - Foundation, Shear walls, Beams, Columns and Slabs.

It is intended to develop a strucural scheme such that the proposed structure is able to satisfy architectural and service requirements and also meet durability, longevity and aesthetic criterias.

It depicts the assumptions and specifications that are being used to develop the documents for a project.

It will also cost help avoid the "Scope Creep" that can affect the project schedule and budget.

(iv)

Types of Analysis options STAAD: -

• Linear Static Analysis
• Second order Analysis (P -△)
• Non-Linear Analysis
• Member imperfection Analysis
• Pushover analysis (Deformation)

(v)

FIXED vs FIXED BUT

When the FIXED support is specified, for those degrees of freedom which are to be treated as fully restrained, STAAD assumes the displacements to be known quantities whose value is zero. Hence, those degrees of freedom are not considered for the stiffness matrix, and their value is not calculated.

For the FIXED BUT support type, if any degrees of freedom are assigned a spring using the KFX thru KMZ terms, those are treated as unknowns and their displacements are calculated.

RESULT: -

1. Explained the structure systems in STAAD Pro

2. Explained the coordinate system adopted in STAAD Pro software.

3. Elaborated DBR and its uses.

4. Explained the different types of analysis options in STAAD pro

5. Explained the difference between Fixed and Fixed But condition.
