Vibration Control And Modeling Of Building Related Structures

Question: Discuss about the Vibration Control And Modeling Of Building Related Structures. Answer: Introduction The most important requirement involved in case of any construction work is the need to measure the safety based parameters of the structure. This will help in protecting the structures associated and the human resources involved with a construction related project against any natural hazards or challenges. For solving the problems associated, the need for the addition of passive or active control is required. In addition, this will also requires the addition of controlling strategy implementation, mathematical modeling formulations and application of controlling devices. This paper lists the various parameters that will be used for the analysis of vibration based applications. Problem statement The modern trends of the civil era have resulted in the development of various buildings for meeting the needs of the growing of the population. These structures are sometimes vulnerable to any hazards or threats which may occur naturally or due to man-made reasons (Mak Wang, 2015). This is the main reason for the increasing demand for addressing the effectiveness of the constructional safety factors. This has also been associated with the measurement of the vibration parameters from the structures associated. Aims and objectives This section includes the aims and objectives of this paper which will be followed for addressing the requirements. The aims of this research paper are to find the associated vibrations parameters from the constructions buildings that will be able to calculate the safety requirements of the structure. The objectives of this paper are as follows: To model the various structures associated to a building To estimate the sensing parameters of the building To successfully mitigate the problems associated with building structures Research methodology The research methodology section is mainly involved with the processes involved in collecting the data and analyzing it. All of these data or information is collected using a specific approach which is used for research methods. This paper has used the descriptive research design processes. In this case, the all the associated sections and the data are carefully analyzed and evaluated such that it can be addressed in this paper. Moreover, this paper will use the involvement of the secondary data collection methods. In this case, the utilization of secondary sources is adopted. These secondary sources are comprised of online journals, newspapers and websites. All these sources will be analyzed using the qualitative data analysis process. Literature review The concerns of the building are mainly due to the need for protecting them from natural or man-made activities. This may include strong winds or construction vibration due to a nearby site. It is required to have the necessary knowledge needed for the dynamics that it is involved with. For determining the concepts involved with the dynamics of the structures, the need to consider the reasons for excitations are required (Kouroussis et al., 2014). For example, the cause of an earthquake are mainly due to the sudden release in energy due to the tectonic movements in the earths crust which results in striking oscillation among the building structures. The output from these sources has been collected using various instruments which successfully shows the data associated. Research design For evaluating the data involved in the dynamic systems, the response from the input and output sensors will be analyzed. The inputs of these processes are the ones collected from the seismic forces. Data collection As stated earlier in this paper, the data associated with this paper will be collected from various secondary sources. These sources are the various online books or journals, government websites and newspaper articles. Data analysis The analysis of the data collected is done by adopting the qualitative data collection methods. This involves analyzing the secondary sources and then making the analysis associated. Secondary data collection and analysis As mentioned before, the data will be collected from the government websites which is responsible for civil engineering based construction projects. The data will also be obtained from various online PDFs and newspaper articles which show an extensive amount of data to be associated. After the successful collection of the data associated, the various information corresponding to building types and names and its associated parameter will be provided in an excel spreadsheet format for clear presentation of the analysis section of the paper.
