Corresponding Author : N. Ahmed (nirob.cee@gmail.com)
Abstract :
Damping has a significant task to diminish the reaction of the structures when exposed to sidelong loads like earthquake loads. There are a few kinds of dampers being used. Among them, Fluid Viscous Dampers (FVD500) is used in this study to evaluate the response of irregular shaped reinforced concrete buildings. Four types of buildings having plan irregularities, namely Box Shaped Building, C Shaped Building, I Shaped Building, and L Shaped Building, are analyzed with FVD500 at the Corners and Exterior…

Abstract :
Traditional construction materials can be engineered from different types of nanomaterials. Out of a wide range of nanomaterials, graphene derivatives, carbon nanotubes (CNTs), nano titanium dioxide, nano silica, and nano iron oxide are attracting immense interests for the application in advancing concrete technology. Herein, this study exemplifies the advancement and compare the possibilities of nanomaterials applications in cement-based composites to develop high performance nano-engineered concrete with multifunctionality. Nano-engineered cement-based composites show the promise for multifunctionally such as high strength, durability…

Abstract :
Bangladesh is one of the most tectonically active regions in the world. It rests where three tectonic plates meet. Recent occurrences of several frequent minor tremors indicate that Bangladesh is at high risk of a devastating earthquake. Most of the buildings in Bangladesh are not constructed following current building codes and in the majority, seismic behavior is not taken into consideration. So, it has become quite vital to quantify earthquake risks and to develop a strategy that will be followed…

Abstract :
Nowadays, while the globe is facing extreme difficulty with COVID-19, Artificial Intelligence can help to cope with this epidemic in an innumerable number of ways. Motivated by this, in this article, a robust prediction model has been proposed for pandemic COVID-19 using Sequential Deep Learning (SDL), called COVID-SDL to predict the total positive cases. The proposed model utilizes the correlation information among the features that have strengthened the prediction capability. In addition, to assist the prediction ability of COVID-SDL, ReLu…
Grey-Taguchi Approach to Optimize Fused Deposition Modeling Process in Terms of Mechanical Properties and Dimensional Accuracy

Abstract :
Fused Deposition Modeling (FDM) is a process that allows for the rapid production of functional parts through the deposition of fused material layers in a sequential manner. FDM has flexibility and the potential to create complicated parts. This study aims to optimize the FDM process parameters in terms of tensile strength, flexural strength, and longitudinal shrinkage using the Grey-Taguchi approach. The input parameters chosen to study the effects on dimension and mechanical properties are layer thickness, the raster angle, fill…

Abstract : Heavy metal pollution and its effects on public health and the environment have led to an increased interest in developing biotechnological approaches. This study was carried out to check the heavy metal biosorption capacity of locally available blue-green microalgae. In this study, microalgae were collected from local ponds and cultured in BG-11 medium. Sixteen different algal doses from 0.2 g/L to 20 g/L were applied to synthetic wastewater and their removal efficiencies of Cr(VI), Ni(II) and Zn(II) were found to…
Estimation of Water Quality in Surma River Using Digital Image Data
Corresponding Author : S.Z. Farzana (zehan_farzana@lus.ac.bd)
Abstract : Typical water quality measuring techniques in Bangladesh are time-consuming, costly, and are not certainly accessible to the general people while it is very essential for ensuring safe water for different household and drinking purposes. In this study, a low-cost digital camera has been used to measure different water quality parameters aimed to shape it as an alternative to the traditional system. Water samples were collected from two points of the Surma River, and subsequent images were taken with camera height…
A Study on the Efficiency of Permeable Concrete with Scrap Tire Rubber
Corresponding Author : M.I. Kabir (imran.kabir-cee@sust.edu)
Abstract : With the advancement of civilization, the volume of polymeric wastes, for example, tire rubber is expanding at a quick rate. This study attempts to utilize this discarded tire rubber to produce permeable concrete for stormwater management in urban area facilitating water sensitive urban design and to compare it with the conventional permeable concrete. In this study, 5%, 10% and 15% coarse aggregate are replaced with shredded tire rubber (as w/w ratio) maintaining a constant water cement ratio of 0.32. It…
Rethinking Urban Retail Spaces due to Covid-19 Pandemic in the context of Sylhet, Bangladesh

Abstract :
Maintaining social distancing is currently an ultimate prerequisite to evade the crowd owing to the Covid-19 pandemic in public spaces like marketplaces, retail shops, parks, and streets. Adopting social distancing is quite thought-provoking mostly in public buildings in Bangladesh since the building design concept allure public gathering, more accessibility, and shared facility. Retail spaces like markets and shopping malls are one of the centers of public crowds where people commonly share facilities and circulation significantly. Apart from social distancing, there…
Evaluate Bearing Capacity of Fixed Type Sand Compaction Pile (SCP) in Clay with the Variation of Clear Distance between Two Successive Piles

Abstract :
Sand compaction pile (SCP) is the economic and less time-consuming technique of ground improvement for most of the countries concerning other piling methods based on the historical data and it is used for the replacement of cast-in-situ, precast, timber, and composite piles. The installation method of SCP is easier and faster than other methods because of less unit weight and no additional materials are inserted during construction. Square patterns of SCP are most suitable and easier to construct than others…
