1RESEARCH PAPERAbstractInto the field of civil engineering, it is critically importance that condition of the buildings isrequired to monitor for detecting of damages that is possible to failure of the civil structure. Theresearch is based on “Investigation on civil engineering applications of Piezoelectric basedsensing techniques in structural health monitoring”. Structural health monitoring is based oncapability of the system to detect and overcome with the structural damages of the buildings. Inthis particular study, piezoelectric based sensing techniques are being used for detection of thedamages. The researcher performed of experimental procedures and did analysis on selectedresearch topic. The analysis is being performed with in-situ damage those are detecting thematerials with use of piezoelectric sensors. Two of the methods are used in this particular studysuch as frequency response method and lamb wave method. Lamb wave methods are used tohandle of the location of the damages. Keywords: Piezoelectric based sensing techniques, Structural health monitoring, Frequencyresponse method, Lamb wave method

3RESEARCH PAPER1.0 IntroductionLiu et al. (2017) stated that infrastructure of civil engineering is most expensivenationwide investment and their structures have longer service life as evaluated to additionalcommercial products. The prototypes into civil engineering and the structure is lead to innovativein terms of design with construction. The important structure of civil engineering includes ofbridges, buildings and dams. Yaphary et al. (2017) demonstrated that the civil structures areequipped with Structural Health Monitoring (SHM) for ensuring of structural integrity as well assafety. SHM aims to develop of automated systems for monitoring, tear down inspection anddamage detection of the civil structures (Tao et al. 2016). SHM system provides real timeinformation, detects defects and monitoring of stress and temperature. It is required to monitorfor ensuring of safety and tough service life. SHM system consists of three components such assensor, data processing and health evaluation system. The first step to set up the system is tointegrate of level of consistent structural sensing ability. Chopra, Nigam and Pandey (2015) cited that SHM system is based on civil structurewhich allows remote monitoring with handling of automated system over inspection cycle toreduce down time. The main focus of this paper is to replace of current cycle to inspect withmonitoring system which tends to increase damage probability before catastrophic failures(Amezquita-Sanchez et al. 2014). Incidents such as collapse of building are rise into variousparts of the world with little warning before it occurs. Due to increase into total number ofbuilding incidents, it becomes important to develop detection methods for reduction of buildingsdamage. Wang, Paur and Ravikovitch (2017) mentioned that buildings as well as criticalinfrastructure are being monitored such as patient into the hospital, signs for degradation,

Grauer and Morelli(2013) stated that intelligent sensors as well as technologies are used to diverse array of the dataand create of structural picture of the buildings that help to determine early detection of thedamage due to natural hazards. 2.0 Research Aims and ObjectivesThe aim of this paper is based on research for designing of SHM for the applications ofcivil engineering. In this paper, it analyzed piezoelectric based sensing techniques for the civilengineering structuressuch as buildings. The structural design of the building is based on varioussensing methods which hold of strengths and weakness to conduct of the building materials. Ituses of insulation materials with damage to fibers. The other aim is to analyze the sensorfunctionality with the service time with extreme loading events. There are various effects thatprovide consequence on wave’s propagation with change of measured impedance spectrum. Thisresearch study is based on effects where both structure bonding as well as sensor is based ontechniques which consist of host structure to monitor the services. Different types of methods areused for health monitoring of the buildings. The main aspect of this paper is to analyzepiezoelectric sensor for civil engineering applications. Following are the objectives for this particular research study:To design of SHM for the applications of civil engineeringTo analyze the sensor technology methods used for health monitoringTo study the damage detection methods able to respond to frequency changemethod
5RESEARCH PAPER3.0 Research questionsFollowing are the questions which are required to analyze in this paper:1.How are Piezo sensors useful for the SHM into civil engineering?2.What are the sensor technology methods which could be used for health monitoring?3.How are the damage detection methods able to respond to frequency change method?4.0 Literature review4.1 IntroductionThe structures of Civil engineering have longer life of service and are very impossible tochange the structure or replace them once they are made. Yan et al. (2017) stated that the civilstructures that are built can deteriorate any time before they are expected to. The structuresmainly deteriorate because of overload, environmental erosion, inspection methods, aging,maintenance lack, excessive use and many more. Civil engineering for SHM (Structural HealthMonitoring) system that is effective can diagnose the defects and location in real time (Hu, X.,Zhu and Wang 2014).This can help to repair the structure and reinforce them in time so that thesafety and structural integrity can be ensured. Methods of SHM (Structural Health Monitoring)systems are applied to structures of civil engineering and to their components at present time. Banerji, Bagchi and Khazaeli (2016) argued that it includes static displacement, methodsof identification, testing and also non- destructive method of testing such as acoustic emission,impedance, X-ray, pulse radar, thermal imaging and ultrasonic. The methods of Structural HealthMonitoring System are mostly qualitative and are difficult to carry out. Talakokula, Bhalla andGupta (2014) demonstrated that the materials that are smart include optical fiber sensor,
