This document presents a comparative study of the seismic performance of waffle slab and conventional slab structures with bracing systems, using time history analysis. A G+4 building model was created in ETABS and earthquake loads were applied from the Chamoli earthquake data. Parameters like joint displacement, storey drift, stiffness, and displacement were compared. Results show that the waffle slab structure performed better with 12% less displacement and 57% lower drift compared to the conventional slab structure. Both structures were within permissible drift limits. However, the conventional slab showed slightly lower storey stiffness. Overall, the study concludes that the waffle slab structure performs better in resisting seismic loads compared to the conventional slab structure when using bracing systems.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

IRJET-Lateral Stability of High Rise Steel Buildings using E TABSIRJET Journal
This document summarizes a study on improving the lateral stability of high-rise steel buildings using different bracing systems. A 15-story steel building model was created and analyzed using ETABS software under wind and earthquake loads, with no bracing, X-bracing, and V-bracing. Results found that displacement was higher without bracing compared to braced models. X-bracing experienced higher lateral loads under wind, while V-bracing performed better under earthquake loads. More research is needed to further evaluate bracing systems for improving lateral stability of high-rise steel structures.

This document presents an analysis of a G+25 reinforced concrete bare framed structure with shear walls under seismic loads. Four models are analyzed with shear walls placed at different locations (intermediate, corner, middle, core) and compared to a conventional structure without shear walls. The objectives are to analyze seismic forces for Zone III and compare bending moments and shear forces. The methodology uses STAAD Pro V8i to model and analyze the structures. Results show that the model with a shear wall at the corner performs best, with bending moments reduced by 37% compared to the conventional structure without shear walls. In conclusion, adding shear walls, especially at the corner, improves a structure's ability to resist seismic forces.
COMPARATIVE SEISMIC ANALYSIS OF A MULTI-STOREY RCC STRUCTURE WITH & WITHOUT F...IRJET Journal
This document discusses a comparative seismic analysis of a multi-storey reinforced concrete structure with and without floating columns located in seismic Zone IV, using computer software ETABS.

Parameters compared include storey drift, displacement, and shear. Results show that the presence of floating columns increases storey drift and displacement due to discontinuity in load transfer, with interior floating columns performing better than exterior columns. The study seeks to evaluate the impact of floating columns on the structure's seismic performance and response.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
