Environmental Flow Assessment of the Sangu River
Corresponding Author : Aysha Akter (aysha_akter@cuet.ac.bd)
Abstract :
The Meandering Sangu River is well-known for its biodiversity and fish habitat. There are six large Bridges (≥100m in length) and a sluice gate over the Sangu River; thus, flow alteration is apparent. The research question is “What are the impacts of water quality due to high and low flow to the Sangu River?” To answer the research question, the specific objective of this project is to conduct an environmental flow assessment of the Sangu River through two phases of…
Study on Seismic Responses of Plan Irregular Buildings Due to Torsional Irregularity and Re-entrant Corners
Corresponding Author : A. Paul (arpice114@gmail.com)
Abstract :
Irregularly shaped buildings are susceptible to seismic load although it has an intrinsic appeal to humans. A lot of research on the irregular configuration of buildings has been conducted to understand seismic behavior but there are no widely accepted guidelines for it. Consequently, ensuring the desired performance of irregular buildings at seismic load is always a challenge for structural engineers. Therefore, to evaluate the seismic performance of irregular buildings, a study was conducted on G+12 storey buildings with four different…
Modeling of Reinforced Concrete Beam-Column Joints in ANSYS to Assess the Impact of Reinforcement Patterns
Corresponding Author : Md. Golam Shahria Bhuyain (shahria_ce@lus.ac.bd)
Abstract :
Most of the RCC failures commonly occur due to inadequate detailing or model design of joints. The fundamental requirement at joints is to ensure that all forces acting at the ends of the members are effectively transmitted through the joint to the supporting members. The junction of beams and columns experiences complex stresses that must be carefully addressed during the design of reinforcement. The main focus of this paper is to evaluate the effectiveness of different types of corner joints…
Scenario Building about the Mindset & Perception of University Graduates in Bangladesh Regarding Entrepreneurship – An Exploratory Study
Corresponding Author : M. H. Kibria (kibria-ipe@sust.edu)
Abstract :
Entrepreneurship plays a significant role in strengthening the socio-economic development of a country. Every country develops its own strategies and plans to promote entrepreneurship development based on its unique socio-economic conditions, economic priorities, and infrastructural strengths. The stimulation for becoming new entrepreneurs among potential people depends on a country's normative, social and cognitive factors. Although the Government of Bangladesh has taken several steps to promote entrepreneurship, the predicted number of new entrepreneurs has not been increased yet. In addition, a…
Prediction and Experimental Validation of Laser Parameters for Fabrications of A Microchannel
Corresponding Author : Mst. Nasima Bagum (nasima-ipe@sust.edu)
Abstract :
Laser beam machining is an effective technology used across industries due to its diverse applications. Laser engraving processes workpieces through chemical ablation, melting, blowing, and evaporation. Identifying the right process parameters to achieve the desired outcome remains a significant challenge. This research identifies the threshold energy and finds the amount of laser energy that does not contribute to material removal by combining finite element analysis (FEA) and the theoretical model. It also predicts the depth and width of the engraving…
Effects of Aspect Ratio and Obstacle Geometry Size on the Thermal Performance of Air inside a Rectangular Cavity
Corresponding Author : Mostafa Rafid (rafid-mee@sust.edu)
Abstract :
In this numerical study, the authors investigated the effect of varying the aspect ratio of a rectangular cavity on mixed convective flow and heat transfer within the cavity with a solid square obstacle in the middle. Both the top and bottom cavity walls are adiabatic. The Left and right vertical walls have a uniform-temperature heat source and sink. The study is done by altering the size of the obstruction and aspect ratio of the rectangular cavity at Richardson numbers ranging…
Effective placement of fluid viscous damper in irregular shaped reinforced concrete buildings
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…

Comparison of Pushover Curves of RC Frame and Shear Wall Structure
Corresponding Author : E. K. Das (emonkalyan.7@gmail.com)
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…
