Abstract: Nepal suffered a massive loss of life and property from Gorkha Earthquake in 2015AD. Many building structures were either partially or fully damaged and most affected were classic buildings and monuments which were constructed without any design consideration and didn’t pose any resistance during the earthquake. After, a broad study and hazard analysis of earthquakes, the Nepal government concluded that the construction methods needed to be revised. The first building regulation in 1994AD known as NBC: 105: 1994 was drafted after the earthquake in 1988 in the eastern part of Nepal. Moreover IS 1893 (Part 1) and IS 13920 codes are still used widely for earthquake resistance design and detailing. But now the Department of Urban Development and Building Construction (DUDBC) has introduced an updated building code of practice NBC 105: 2020 for earthquake-resistant design. In this paper, an effort is done to analyse and compare the effects on buildings of 2-Storey and 3-Storey under the application of IS and NBC code. Equivalent static analysis was carried out with the help of ETABS v19.1.0 and the parameters like base shear, storey displacement and storey drift under both codes are compared. The analysis result shows that the response of building subjected to NBC: 105: 2020 exhibits higher storey responses compared to IS 1893: 2016. Also, the NBC code demands a higher percentage of reinforcement requirements compared to IS code.

Keywords: Storey Displacement, Storey Drift, Base Shear, Reinforcement Requirement.

Tamirat Kebede, Lecturer, Department of Structural Engineering, Haramaya Institute of Technology, Haramaya University, Ethiopia.

Abstract: In this study, the internal forces, parametric stability and free vibration of elliptic parabolic shell analysis are performed by theoretical and finite element methods. Geometrical and material linearity is considered in modeling and analysis of the structure. Theoretical analysis is done by shallow shell theory and the finite element analysis is carried out by using DLUBAL RFEM 5.3.1. Theoretical formulas in this study are coded by the MATLAB program. The parameter considered thickness, dimension, radius of curvature, modulus of elasticity and side height of the shell for determining the critical buckling load and thickness for free vibration. The internal forces, displacement, critical buckling load and free vibration analysis of result in the study presented graphically and discussed in detail. The result of the finite element analysis is then compared with the theoretical analysis results.

Keywords: Elliptic Parabolic Shell, Parametric Stability, Free Vibration Analysis, Theoretical Analysis, DLUBAL RFEM Analysis, MATLAB program.

Impact of Strong Column Weak Beam for a Six-Story Residential Building According to Indian Code
Ashish Poudel

Abstract: Ductile design and detailing provisions were revised in 2016 by the Bureau of Indian Standards. It introduced Strong Column Weak Beam Provision (SCWB) for beam-column joint. In this paper, an attempt is done to investigate the influence of SCWB provision on the Longitudinal Rebar Quantity (LRQ) of typical columns i.e. Corner Column, Edge Column, and Middle Column on seismic Zones III, IV, and V for six-story buildings. Story-wise variation reached a maximum from 100% to 200% in the 4th and 5th story whereas overall variation was observed from around 50% to 80% in LRQ of the column while considering SCWB over the conventional technique of column design. Finally, the study concludes that the requirement for design strength ratio i.e. Beam column capacity ratio has resulted in excessive quantity of rebar and thereby increasing its cost specifically for the residential buildings and apartments of smaller heights.

Keywords: Strong Column-Weak Beam, Longitudinal Rebar Quantity, Ductile Design and Detailing, Typical Column.
