Our current 21st century has seen more drastic changes in terms of environmental conditions due to global warming, climate change and deforestation. This has shown a great rise in the global temperature throughout the world. Normally, the roof top of a building is provided with tiles to protect the structural components and to create a comfortable environment. The tiles can be made of materials like clay, concrete, fly ash, lime etc. Due to the prevailing environmental challenges, there is a need for the tiles to be made as with more energy efficient material that supports thermal insulation and cost effectiveness. Aerogel and hydrogel are the gel based product that are used in our current work to enhance the thermal insulation property of the tiles. Various tests such as water absorption test, wet and dry cycle test, bending strength test, thermal conductivity test, wear and tear test are carried out on the tile to quantify its characteristics. All the above shows better value than the normal commercial tile product.
目前的21世纪,由于全球变暖、气候变化和森林砍伐,环境条件发生了更剧烈的变化。这表明全球气温在全球范围内急剧上升。通常情况下,建筑物的屋顶是用瓦片来保护结构部件和创造一个舒适的环境。瓷砖可以由粘土、混凝土、粉煤灰、石灰等材料制成。由于当前的环境挑战,需要使用更节能的材料来制造瓷砖,以支持隔热和成本效益。气凝胶和水凝胶是凝胶基产品,在我们目前的工作中用于增强瓷砖的隔热性能。对瓷砖进行吸水试验、干湿循环试验、抗弯强度试验、导热系数试验、磨损试验等各种试验,量化其特性。这些都显示出比普通商业瓷砖产品更好的价值。

Greenhouse gases emissions are very important for every structure and environment. Greenhouse gases are increased now a days due to changes in climatic conditions by involving human activities in the last decades. In this main contributor is carbon content and carbon dioxide and methane in the environment. The main solution is to limit the changes in the climatic conditions. To reduce the use of carbon emissions in construction of Buildings and construction of Industrial structures. Structures which are made from timber and steel are produce less carbon and greenhouse gases compared to the concrete and steel structures. By using reused and recyclable materials we can reduce the carbon footprints and greenhouse gases as well as to develop low carbon materials. We need to design low carbon buildings to avoid climatic changes in the environment. Which will be give renewable performance. This paper gives a knowledge and help to reduction of carbon footprints on buildings. The main concept of this paper is reducing the emissions and reduce the carbon footprints and increase the life of the structure and to make the structure sustainable.
温室气体排放对每个结构和环境都非常重要。由于过去几十年的人类活动导致气候条件的变化,温室气体现在每天都在增加。其中的主要贡献者是环境中的碳含量、二氧化碳和甲烷。主要的解决办法是限制气候条件的变化。减少建筑及工业建筑的碳排放。与混凝土和钢结构相比,由木材和钢材制成的结构产生的碳和温室气体更少。通过使用可重复使用和可回收的材料,我们可以减少碳足迹和温室气体,并开发低碳材料。我们需要设计低碳建筑来避免环境中的气候变化。这将具有可再生性能。本文为减少建筑物的碳足迹提供了知识和帮助。本文的主要思想是减少排放,减少碳足迹,增加结构的寿命,使结构可持续发展。

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 ( 1.4 c b MM) has resulted in excessive quantity of rebar and thereby increasing its cost specifically for the residential buildings and apartments of smaller heights.
2016年,印度标准局对延性设计和详细规定进行了修订。介绍了梁柱节点的强柱弱梁配置。本文试图研究在III、IV和V震区六层建筑中,SCWB设置对典型柱(角柱、边柱和中柱)纵向钢筋量(LRQ)的影响。在第4层和第5层,故事间的变异达到最大值,从100%到200%,而在考虑SCWB而不是传统的柱设计技术时,在柱的LRQ中观察到的总体变异约为50%到80%。最后,研究得出结论,对设计强度比的要求,即梁柱容量比(1.4 c b MM)导致钢筋数量过多,从而增加了其成本,特别是对于较小高度的住宅建筑和公寓。

Comparative Study of Building Response on Adoption of NBC105: 2020 and IS 1893 (Part 1): 2016 采用NBC105: 2020和IS 1893的建筑响应比较研究(第一部分):2016

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.
尼泊尔在2015年的廓尔喀地震中遭受了巨大的生命和财产损失。许多建筑结构部分或全部受损,受影响最严重的是经典建筑和纪念碑,这些建筑没有任何设计考虑,在地震中没有任何抵抗。经过广泛的研究和地震危害分析,尼泊尔政府得出结论,施工方法需要修改。1994年的第一个建筑法规被称为NBC: 105: 1994,是在1988年尼泊尔东部地震后起草的。此外,IS 1893(第1部分)和IS 13920规范仍然广泛用于抗震设计和细节设计。但现在,城市发展和建筑建设部(DUDBC)推出了一项更新的建筑实践规范NBC 105: 2020,用于抗震设计。本文分析比较了is和NBC规范对2层和3层建筑的影响。利用ETABS v19.1.0进行等效静力分析,对两种规范下的基础剪力、层位移、层位移等参数进行比较。分析结果表明,与IS 1893: 2016相比,受NBC: 105: 2020约束的建筑表现出更高的层数响应。此外,与IS规范相比,NBC规范要求更高比例的加固要求。

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.","PeriodicalId":356159,"journal":{"name":"Indian Journal of Structure Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127030403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
本文采用理论和有限元方法对椭圆抛物壳的内力、参数稳定性和自由振动进行了分析。在结构的建模和分析中考虑了几何线性和材料线性。理论分析采用浅壳理论,有限元分析采用DLUBAL RFEM 5.3.1软件。本研究的理论公式由MATLAB程序编码。该参数考虑了壳体的厚度、尺寸、曲率半径、弹性模量和侧高,以确定自由振动的临界屈曲载荷和厚度。对研究结果的内力、位移、临界屈曲载荷和自由振动进行了图解和详细讨论。将有限元分析结果与理论分析结果进行了比较。
