‘STRAP’ is one of the most comprehensive and versatile structure; analysis and design software systems available in the market – today. It is also easiest to use, due to superb graphic user interface (GUI) and context sensitive help system. It offers the engineer a power but affordable tool for analysis and design of a wide range of skeletal and continuum structures, such as buildings, bridges, shells, towers and more.
“STRAP” comes with design modules for designing reinforced concrete, post tensioned concrete, structural steel dynamic effects module for modal analysis seismic response spectra calculations according to many codes and time history response calculations.
The learning curve to start using strap is practically non-existent the programs flows is similar to the analysis and design process performed by hand . during the execution of every action the prompt line all the bottom of screen guides us through combine this with the context-instinctive help.
1) Wall element option enables the simple and quick definition of a core/shear wall that extends the height of building .
2) STRAP includes advanced analysis features such as tension and compression only beams, non linear and semi rigid beam connections, non-linear cables, gap elements, P – Delta Analysis.
3) A model analysed and designed by STRAP may bc interactively detailed using Beam D.
4) Footing module designs reinforced concrete spread footings in which a single table displays the footings in data for all footings (or) default parameters are defined for the project and defined parameters may be defined for selected footing.
1) Checking of Input Data
After Preparation of Strap building model, its data shall be checked thoroughly by various commands available in Strap software for its correctness.
2) Running of Analysis
It gives results for various load combination cases provided to it. To give results for various load combinations with the appropriate load factors as per IS 456-2000 and IS 1893-2002.
Program Output Gives values of Axial force, Moment, Shear force and Deflections for each member like, column, beams, shear walls, plates.
3) Output results from the Program
The results obtained by Program should thoroughly checked before accepting the same in the final design.
a) The checking of input data is already discussed.
b) Checking of Displacements.
i) For fixed end of a Frame the value of displacement must be zero.
ii) The max horizontal displacement due to earth quake forces between successive floors shall not exceed 0.004 times the difference in levels between the floors.
iii) Displacement of all joints on a particular floor should be equal (Rigid Diapharam).
iv) While checking of forces, at every joint. Following 3 equilibrium equations must be satisfied.
a) Sum of all vertical forces must be zero.
b) Sum of all horizontal forces must be zero.
c) Sum of all moments at the joint must be zero.
Note : Designer should personally check these points and check some joints for his own satisfaction.
4. Design of various RCC Elements of Building
After Analysis is over, thoroughly checked, the detailed design of various members of the building in the following order of Actual construction, to be in tune with construction program decided by the Project Managers at site.
i) Design of piles or pad footings, raft (Depending on the site and foundation condition).
ii) Design of columns.
iii) Design of beams (plinth level to term).
iv) Design of slabs (1st slab to Terrace).
v) Design of Staircase,
vi) Design of Water Tank, Lift Machine room, stair case head room.
Civil Engineering students who seek to step into the Structural Engineering career line and to learn high rise and Iconic building designing to fetch job around.
