An axial compression check refers to the analysis and assessment of columns&Inclined structural members resisting earthquake in which the factored axial compressive stress considering all seismic load Combinations shall be limited to 0.4fck (fck=characteristic Compressive strength of concrete ).The purpose of this check is to ensure that the member can safely withstand the applied compressive load without experiencing excessive deformation or failure during an earthquake

The axial compression check involves evaluating the capacity of the member to resist compressive forces through various design considerations, such as material properties, cross-sectional dimensions, and support conditions. The key parameters considered during this analysis typically include the following:

1.Axial load: The magnitude and distribution of the compressive load applied to the member are determined based on the structural design requirements.

2.Cross-sectional properties: The dimensions and shape of the member’s cross-section, such as its area, moment of inertia, and radius of gyration, are crucial for assessing its ability to resist compression.

3.Material properties: The mechanical properties of the material used for the member, such as its yield strength and modulus of elasticity, play a significant role in determining its compressive capacity.

4.Buckling analysis: The axial compression check also involves evaluating the member’s susceptibility to buckling, which refers to the sudden failure caused by lateral instability when subjected to compressive loads. Buckling analysis considers factors such as the effective length of the member, end conditions, and slenderness ratio to ensure stability.

By performing an axial compression check, we can determine whether the member is designed appropriately to safely carry the applied compressive load. This analysis helps ensure structural integrity, prevent collapse, and maintain the desired safety margins in a construction project.
