Steiner theorem in brief: The second moment of area is a cross-sectional property of a plane figure with respect to a given axis, describing its resistance to bending. Steiner’s theorem (the parallel-axis theorem) makes it possible to calculate the second moment of...
Second moments of area of plane figures in brief: Calculating the second moment of area of an I-section requires dividing the cross-section into three rectangles: two flanges (top and bottom) and one web. The first step is to determine the centroid of the entire...
Internal forces in beam in brief The calculation process starts by determining the support reactions using the three equations of static equilibrium. The beam should be divided into characteristic spans, whose boundaries are defined by the locations of point loads,...
Gerber beam in brief A Gerber beam is a system of beams connected by hinges, which makes it possible to create statically determinate multi-span structures. The analysis should begin by dividing the structure into component beams at the hinge locations. A key step is...
Beam calculations in brief: Beam calculations are based on determining support reactions and internal forces, which makes it possible to verify the safety and strength of the structure. Every analysis should start by checking static determinacy, to ensure that the...
