Design is the main strength of Willus Infrastructure. Two of the three directors have worked as Heads of Design in leading PEB companies. This strong background helps us work as one of the trusted Pre Engineered Buildings Manufacturers in India. We focus on safe, strong and cost effective design for every project.
As experienced Pre Engineered Buildings Manufacturers in India, we use the stiffness matrix method to analyse the main framing system. The design follows the Allowable Stress Design method. We follow standards such as AISC and IS 800. Our design program helps us create an economic and efficient frame design.
We are known among leading Pre Engineered Buildings Manufacturers in India because our software allows different design modes. It helps in deciding frame geometry, loading details and required load combinations as per the selected building code. The program runs many cycles to achieve a safe and acceptable design result.
As reliable Pre Engineered Buildings Manufacturers in India, we calculate displacements and internal forces using the stiffness matrix method. This gives correct values for moments, shear forces and axial forces in every member of the frame.
A) Design Cycle
Being responsible Pre Engineered Buildings Manufacturers in India, we follow a clear design cycle:
- 1. We decide section sizes and brace locations based on building shape and loading.
- 2. We calculate moment, shear force and axial force at every point for each load combination.
- 3 We check allowable shear stress, axial stress and bending stress in both compression and tension.
This step by step process makes us dependable Pre Engineered Buildings Manufacturers in India for safe structures.
B) Frame Loading
As professional Pre Engineered Buildings Manufacturers in India, we design frames to handle different types of loads:
- 1. Dead loads from roof sheets, purlins and self weight of the frame.
- 2. Live loads with proper load reduction where required
- 3. Collateral loads such as false ceiling, lights, AC ducts and sprinkler systems.
- 4. Wind loads based on basic wind speed or pressure as per selected building code.
- 5. Codes such as MBMA, UBC, ANSI and IS 875 Part 3 are used.
- 6. Crane and non crane loads can be added and combined with other loads.
- 7. Seismic loads based on zone category can be defined and combined.
- 8. Temperature loads can be added using thermal expansion values.
- 9. Load combinations with required load factors can be created.
This detailed loading study makes us strong Pre Engineered Buildings Manufacturers in India who focus on safety.
C ) Design Codes
As trusted Pre Engineered Buildings Manufacturers in India, we follow major international and Indian standards:
- • AISC – American Institute of Steel Construction
- • AISI – American Iron and Steel Institute
- • MBMA – Metal Building Manufacturers Association
- • ANSI – American National Standards Institute
- • ASCE – American Society of Civil Engineers
- • UBC – Uniform Building Code
- • IS – Indian Standards
Following these codes helps Pre Engineered Buildings Manufacturers in India maintain global quality levels.
D ) Design Criteria
As experienced Pre Engineered Buildings Manufacturers in India, we follow clear design criteria:
- • Design Method: Allowable Stress Design method as per AISC specifications.
- • Deflections: Deflection limits follow MBMA, AISC and standard industry practices.
- • Primary Framing: Moment resisting frames with pinned or fixed base connections.
- • Secondary Framing: Cold formed Z or C sections are used for purlins and girts. These act as continuous beams with proper lap connections.
- • Longitudinal Stability: Wind load from end walls transfers through roof purlins to braced bays. Diagonal bracing carries the load safely to the foundation.
Design Software
Leading Pre Engineered Buildings Manufacturers in India use advanced software for better results. We use STAAD Pro and MBS for structural design and analysis. These tools help us achieve accurate and fast calculations.
Design Process
As systematic Pre Engineered Buildings Manufacturers in India, we follow a clear process:
- • Frame data is created based on members, joints and degrees of freedom.
- • Support conditions and material properties are defined.
- • Member section properties are calculated.
- • The overall stiffness matrix is formed by combining individual matrices.
- • Load vectors are created based on applied loads.
- • Unknown displacements are calculated by solving the stiffness matrix.
- • Internal forces are then obtained for design checks.
This detailed method ensures safe and efficient buildings.
Validation Process
The validation process separates major Pre Engineered Buildings Manufacturers in India from small companies. Every design is checked and approved by senior structural engineers. Each stage is documented carefully to reduce errors and improve quality.
Detailing Process
As advanced Pre Engineered Buildings Manufacturers in India, we use 3D detailing software. This gives accurate drawings and clear erection details. It also supports faster fabrication and proper dispatch planning. The 3D process helps in smooth site installation and better project control.
Willus Infrastructure works with strong technical knowledge, advanced tools and strict validation systems. This approach makes us one of the dependable Pre Engineered Buildings Manufacturers in India, focused on safety, quality and long lasting structures.
