Design Overview

Design is the core strength of Ameya Group, with two of the three directors having previously led design efforts at major PEB companies. We analyze the main framing of PEB systems using the stiffness matrix method. Our design adheres to allowable stress design (ASD) standards set by the American Institute of Steel Construction or IS 800. Our design program offers an economical and efficient approach to creating main frames.

  1. Determine the sizes of sections and the locations of braces according to the frame design's geometry and loading requirements.
  2. Calculate the moment, shear, and axial force at each analysis point for every load combination.
  3. Assess the allowable shear, axial, and bending stress in both compression and tension at each analysis point.
  4. Calculate the stress ratios for shear, axial, and bending by comparing actual stresses to allowable stresses, and then determine the combined stress ratios.
  5. Identify the best splice location and verify that the proposed sizes meet manufacturing requirements.
  6. Use the web optimization mode to find the ideal web depths for the next cycle and update the member data file accordingly.
  7. After completing all design cycles, conduct an analysis to optimize the flange braces.
B) Frame Loading
  • The total dead loads from sheeting, purlins, and the frame's own weight.
  • Additional collateral loads, including false ceilings, light fixtures, air conditioning ductwork, sprinkler systems, and other similar suspended elements.
  • The frame is subjected to live loads, including tributary reductions.
  • Users can specify both crane and non-crane loads, and the program can effectively manage these special loads, combining them with other necessary loads.
  • Users can input wind loads, such as basic wind speed or basic wind pressure, which will be converted to design wind pressure according to the specified building code. These pressures will then be applied to various building components based on the coefficients outlined in the chosen codes.
  • Standard building codes, including MBMA, UBC, ANSI, and IS:875 Part 3, are utilized for this purpose.
  • Users can also define seismic loads based on different zone categories from various international codes and combine them with other load cases as needed.
  • Additionally, users can specify temperature loads by providing different differential temperature values in degrees Celsius and selecting the appropriate coefficient for thermal expansion.
  • Users have the flexibility to define load combinations with the desired load factors..

D) Design Criteria

The allowable stress design method follows the AISC specifications.

Unless stated otherwise, the deflections will adhere to MBMA, AISC guidelines, and standard industry practices.

Moment resisting frames with pinned or fixed bases.

Cold-formed Z or C sections are used for purlins and girts, designed as continuous beams that span across rafters and columns with overlapping connections.

Wind load on end walls is transferred via roof purlins to the braced bays, which then direct the load to the foundations through diagonal bracing.

The most recent software utilized includes STAAD Pro and MBS.

Frame data consists of members, joints, degrees of freedom (DOFs), restraints, and elastic properties. To find the unknown displacements, we calculate the joint stiffness matrix, invert it, and then multiply it by the load vector.

Every design undergoes thorough documentation and validation by senior structural engineers to prevent errors. This process sets major PEB companies apart from their smaller counterparts.

Ameya Group utilizes cutting-edge 3D detailing software to provide precise details, quick erection drawings, and efficient dispatch sequencing.
