Week 1 Challenge

A. 1. 1. Open staad pro software , enter share option there its available , go to utilities , command file gives all details of the structure

2. The following are materials

3. yes, take a picture option is available in staad pro

4.you can create model by analytical, physical and building

5. After creating geometry of section property(beam, column etc) ,then assigning properties to the material of required dimension ( rectangluar, circle, general , trapezoidal etc).

2. 1. Effective span , Stiffness , main reinforcement , maximum diameter of bars, spacing of main bars, distribution reinforcement.

2.

3. Go to view option , you will find isometric view, top, bottom , right, left , front , and back click on the icon

4. create geometry of section as number of nodes give dimensions as required , select cursor and join the nodes and assigning support, material and specification defined

5. Introduction, structural layout , loads and combinations, analysis and design methodology , appendix

6.

3. 1. space has 3d in x,y, z axis any kind of joints are assigned. plane is 2d x,y plane , frame 2d loading is perpendicular , truss is 3d , it can take pinned supports

2. Global coordinate system where X,Y,Z follows orthogonal right hand rule. This system defines joint location and load directions. local coordinate system defines plane into two cross sectional direction

3. Design basis report specifies and compile data required for analysis and design of structural elements of the project , it depicts assumptions and specification that are used to develop the construction documents for a project. It will also help to aviod scope creep that can derail the project schedule and lead to budget overruns.

4. perform analysis does linear static force analysis used for building primary load cases is first order analysis, P-delta analysis calculates with respect to applied load and delta the deformation of governing load under building is second order iteration analysis , perform cable analysis every memeber is assigned as cable and its a iterative process, perform imperfection analysis where member is imperfect and chamber is assigned , non linear analysis it is not applicable to solids , generate floor spectrum analysis is used for high rise buildings asserted under load diaghram .

5. fixed supports carry vertical and horizontal forces as well moments also known as rigid supports, fixed but supports have spring constant along each respective forces and moments
