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…
Why do we use diaphragm in ETABS
The main purpose of using diaphragm is to transfer the lateral load to the system. This will only be used when you are having slabs but when your model doesn’t have slab then the lateral forces needs to be applied at the joint Slab possess very high resistance to lateral…
The Statue of Unity
Structural design features of the world’s tallest statue: The Statue of Unity. The ‘Statue of Unity’ is dedicated to the Iron Man of India, Sardar Vallabhbhai Patel. The height of Statue 182 meters. The slenderness ratio varies from 16 to 19. Structural system: Two partly joined cylindrical composite core surrounded…
Bubble Deck Slab
Bubble Deck is a biaxial technology that increases span lengths and makes floors thinner by reducing the weight while maintaining the performance of reinforced concrete slabs. The concept is based on the fact that the area between columns of a solid slab has limited structural effect beyond adding weight. Replacing…
