In various industries, the effect of fluid on the structure and vice versa is necessary to investigate such as shipbuilding, ocean energy sources, offshore structures, etc. In this paper, the dynamic behavior of a long rectangular plate located on a viscoelastic bed at the bottom of a narrow channel has been studied in detail. According to earlier studies, the muddy seabed of coasts attenuate the waves. Here we investigate the interaction between the gravity sea waves and the muddy seabed by modeling the seabed as a rectangular plate that located on a viscoelastic foundation which contains springs and dampers. The springs and dampers are attached at the bottom of plate to model the behavior of the muddy seabed. The governing equations of motion have been obtained and a new semi-analytical solution has been presented to solve them. The proposed model is validated against available literatures. Then, the influence of different parameters such as boundary conditions, plate's rigidity and mass, damping ratio, restoring force and different transverse modes on the vibrational behavior of the system has been investigated in detail. The effects of various parameters on the frequency response of the system have been studied in detail.https://www.jcepm.com/article_115529_468063942633725aabc75fb3c94af539.pdfPouyan PressComputational Engineering and Physical Modeling2588-69593420201001Cylindrical Bending of Power Law Varied Functionally Graded Laminate Subjected to Thermo-Mechanical Loading203911553010.22115/cepm.2020.243741.1124ENSharawari PrafullaKulkarniResearch Scholar, Structural Engineering Department, Veermata Jijabai Technological Institute, Matunga, Mumbai 400 019, India0000-0002-2626-6400Sandeep ShivramPendhariAssociate Professor, Structural Engineering Department, Veermata Jijabai Technological Institute, Matunga, Mumbai 400 019, India0000-0001-9492-5474Journal Article20200813In this paper, efforts have devoted to developing heat conduction formulation to determine the exact temperature for power law varied functionally graded (FG) laminate. Further, the semi-analytical approach has re-invented for displacement and stress analysis of FG laminate. This way of analysis involves solving of two-point boundary value problem (BVP) ruled by first-order ordinary differential equations (ODE's). Here material properties such as modulus of elasticity, coefficient of thermal expansion, and heat conductivity have considered being varied as per power law, whereas Poisson’s ratio kept constant. The effect has undergone examination for applied transverse thermal loading and mechanical loading with the developed semi-analytical formulation. The observation of the effect of variation of volume fraction as per power law on through thickness temperature distribution along with consideration of exact temperature and with assumed power law temperature has carried out. Further corresponding thermal stress analysis and its comparison with numerical parametric studies lead to productive output in this area of research.https://www.jcepm.com/article_115530_cfa07bf54b4175917e81a5b3b768f2aa.pdfPouyan PressComputational Engineering and Physical Modeling2588-69593420201001Numerical Analysis of Reverse Dip-slip Fault Rupture on Steel Buildings405711093610.22115/cepm.2020.225647.1097ENMohammad JavadShabaniAssistant Professor, Faculty of Engineering, Tabari Institute of Higher Education, Babol, IranSaed HabibiM.Sc., Department of Engineering, Tabari Institute of Higher Education, Babol, IranLeila KalaniAssistant Professor, Faculty of Engineering, Tabari Institute of Higher Education, Babol, IranJournal Article20200405In seismic events, rupture resulted from the earthquake causes two types of ground deformation, namely, the permanent pseudo-static deviations on fault and transient dynamic fluctuations away from fault. Fault rupture extends in soil through bedrock and makes various concerns for structures made by human. On this basis, we examined reverse fault effect on ground-level buildings using numerical analysis and ABAQUS finite-element software. In this regard, some types of buildings were placed on ground near to fault and fault route angle was examined in the presence and absence of building in two layers of soil with different densities. Finally, vertical deformation of ground, horizontal strain of ground, lateral displacement of building, and bending moment of structure were examined beneath fault effect. Results reveal that fault route angle depends on soil layer material, and horizontal strain resulted from fault effect on ground increases by placing building. However, vertical displacement of ground will decrease by placing overhead (building) and the highest part of fault effect will be on columns of first floor.https://www.jcepm.com/article_110936_266481ef64af6cebee335004bfdd2502.pdfPouyan PressComputational Engineering and Physical Modeling2588-69593420201001A Circumstantial Review on Ride-sharing Profile in Dhaka City587611552810.22115/cepm.2020.236247.1112ENHasib ImranTusherDepartment of Civil Engineering, Rajshahi University of Engineering and Technology, Rajshahi, Bangladesh0000-0003-1599-2850Arif HasnatDepartment of Civil Engineering, Rajshahi University of Engineering and Technology, Rajshahi, BangladeshFaysal IbnaRahmanDepartment of Civil and Environmental Engineering, University of Yamanashi, Kōfu, Yamanashi, JapanJournal Article20200622The ride-sharing profile has gotten a decision to the horde of Dhaka City in the transportation field because of its broadened habits in transport offices. Before developing ride-sharing, broad issues like traffic blockage, misconduct of the conductors, and tolls' vexation were exceptionally regular in the city's common travel framework. The ride-sharing platform brings mollification in the city's transportation part through the possible relief of such basic practices. The paper aims to grant an itemized vision regarding the ride-offering plan in Dhaka City to how this vehicle framework executes various transportation issues, a couple of downsides, and some innovation-based achievements recommended by the researchers rising bothers of this new vehicle framework. The study also deals with the measures to make the ride-sharing scheme supportable in the future and includes the improvement of some application-based plans like ride-sharing. There is a gigantic extent of study for future researchers concerning the ride-sharing profile in Dhaka City.https://www.jcepm.com/article_115528_e1f9ef8246ac1c5b87329a07c82198e3.pdfPouyan PressComputational Engineering and Physical Modeling2588-69593420201001Stabilization of Ikpayongu laterite using Cement, RHA and Carbide Waste Mixture for Road Subbase and Base Material779611553110.22115/cepm.2020.238161.1114ENSunday UgochukwuAzunnaCivil Works Department, Ringo Star Ventures Ltd, 34 Panama Street Ministers Hill, Maitama, Abuja, Nigeria0000000190374847Emmanuel OkechukwuNwaforDepartment of Civil Engineering, Faculty of Engineering, Nigeria Army School of Technology and Environmental Studies, Makurdi, Nigeria0000-0002-5177-4941Sylvester OOjoboDepartment of Civil Engineering, Faculty of Engineering, Benue State Polytechnic, Ugbokolo, NigeriaJournal Article20200705This research work mainly focuses on stabilization of Ikpayongo laterite using cement blended with Rise Husk Ash (RHA) and Carbide Waste (CW) to promote its physical characteristics. The blending of cement with Rice Husk Ash (RHA) and carbide waste (CW) was done in proportion to determine the required proportion suitable for the stabilization of Ikpayongo laterite. Atterberg limit test, Compaction test, California Bearing Ratio (CBR) test, Specific Gravity, Unconfined Compressive Strength (UCS) test and Durability test were conducted on the laterite sample. The blend of cement with RHA and CW at interval of 0% to 10% displayed better results than the cement treated soil at some percentages. The result showed that at 2% and 10% cement content the MDD of the natural soil reduced from 2.015Mg/m3 to 1.917Mg/m3 and increased to 1.987Mg/m3 respectively, it also reduced to 1.870Mg/m3 when treated with 2% blend of 80% cement 10% RHA 10% CW and increased at 10% of the cement blend. The CBR value of the natural soil was gotten to be 9.66% but increased by 2% when treated with 100% cement. The blend of 80% Cement, 10% RHA and 10% CW yielded the most promising result as CBR value increased from 28% for the natural soil to 97.55% for stabilized soil while UCS increased from 1512.09KN/m2 to 1753.39KN/m2 by volume at 10% of the blends for 14 days cured sample. Based on the results, 80% Cement, 10% RHS and 10% CW is recommended for use in soil stabilization.https://www.jcepm.com/article_115531_f3785075a4c20bc52db67f443b9cc14a.pdf
