Interaction Diagram in a column is a graph which shows a plot for the axial load Pn that a column could carry versus its moment capacity, Mn. This diagram is very useful in analyzing the strength of column which varies according to its loads and moments. This can easily be…

Why Modal Analysis Is Important for Designing of High-rise Structures?
Modal analysis is linear dynamic analysis method which provides the greatest contribution to structural response and behavior of structure after hitting earthquake. According to IS 1893-2016 CLOUSE NO.7.7.5.2 and table no. 6 the first two-mode of vibration is always translation mode unless and until building shape is very irregular. The…
How to Do Errorless Modeling in E-tabs?
HOW TO DO ERRORLESS MODELING IN ETABS? Many structural engineers have faced errors in modeling. It is a common problem that comes while modeling very complex modeling like the model with a different floor plan. 1. WHY ERRORS IS OCCURS? ETABS is sensitive software. if the beams or columns…
Why Stiffness Modifier is Needed for Concrete Frame System?
STIFFNESS MODIFIERS According to IS 16700-2017- Clause no. 7.2 table no.6, UBC-97 Clause 1910.11.1 and ACI 318-19 Clause no. 6.6.3.1.1 table no.6.6.3.1.1 (a) and (b). The Stiffness Modifier values are given. 1. WHY STIFFNESS MODIFIER IS NEEDED FOR CONCRETE FRAME SYSTEM? Concrete has an inherent property of losing itself stiffness…
P-delta Analysis
P-delta is a geometric non-linear effect that occurs in structures that are subjected to compressive loads and lateral displacement. Under the action of compressive loads and lateral displacement, tall slender structures will experience additional stresses and deformations due to the change of position of the structure. First-order structural analysis will…
