Design of Faisal Shine Pre Engineered Buildings (PEB)
The main framing of PEB systems is analysed by the stiffness matrix method. The design is based on allowable stress design (ASD) as per the American institute of Steel Construction specification or the IS 800. The design program provides an economic and efficient design of the main frames and allows the user to utilize the program in different modes to produce the frame design geometry and loading and the desired load combinations as specified by the building code opted by the user. The program operates through the maximum number of cycles specified to arrive at an acceptable design. The program uses the stiffness matrix method to arrive at an acceptable design. The program uses the stiffness matrix method to arrive at the solution of displacements and forces. The strain energy method is adopted to calculate the fixed end moments, stiffness and carry over factors. Numerical integration is used.
The design cycle consists of the following steps:
- Set up section sizes and brace locations based on the geometry and loading specified for the frame design.
- Calculate moment, shear, and axial force at each analysis point for each load combination.
- Compute allowable shear, allowable axial and allowable bending stress in compression and tension at each analysis point.
- Compute the corresponding stress ratios for shear, axial and bending based on the actual and allowable stresses and calculate the combined stress ratios.
- Design the optimum splice location and check to see whether the predicted sizes confirm to manufacturing constraints.
- Using the web optimization mode, arrive at the optimum web depths for the next cycle and update the member data file.
- At the end of all design cycles, an analysis is run to achieve flange brace optimization.
