The Impact

Residential homes are of exceptional significance after any natural calamity which encompass earthquake. The structural and non-structural additives need to stay operational and secure after earthquake. So you can mitigate the impact of earthquake at the structure the bottom isolation method is the splendid opportunity as a seismic protecting system. The primary concept of base isolation gadget is to lessen the earthquake brought on inertia forces by using growing the fundamental length of the structure. Base isolation is one of the most effective tools of engineering concerning the passive structural vibration control technologies. It is supposed to allow a building or non-building shape to continue to exist a probably devastating seismic impact thru a right preliminary design or next changes. In some instances, software of base isolation can improve each a structure's performance and its seismic sustainability notably. he behaviour of multi-storey building of ordinary and abnormal configuration beneath earth quake is complex and it varies of wind masses are assumed to behave concurrently with earth quake loads. On this paper a residential of multi-storey constructing is studied for earth quake with base isolation approach using SAP 2000.

Abstract Necessity of constructing multi-storied buildings is increasing these days. But they are more prone to severe damage due to earthquakes. Base isolation is one of the most powerful tools pertaining to the passive structural vibration control technologies. The structure above the ground, is separated from the effects of earthquake forces by introducing a mechanism that helps the structure to hover. This project deals with analysis of 10 storey RCC, Steel and Composite structures of different shapes with and without base isolation in various seismic zones by Response Spectrum Method using ETABS software. Lead rubber bearings designed as per UBC97 was used for base isolation. Plus shape was found to be most suitable for base isolation for RC structure, whereas for steel and composite structures rectangular and hollow shapes were found suitable. It was also observed that concrete structure performs best when base isolated, compared to other structures.

The Impact

The work presented in this paper bears on the feasibility and the operative technology of embedding electro-rheological (ER) fluids into cement mortar. We have made a cantilever mortar beam with controllable ER fluids filled in a central crack for the purpose of investigation on the evolutional rule of frequencies under different electric field strength by hammering test. The experimental results indicated that the influence of electric field strength upon the first frequency is more evident than that upon the second one, whereas that upon the third frequency is very little. In addition, the physical mechanism of the impact of the change of voltage on the frequency of smart beam structures embedded with ER fluids was discussed. This research sets up an experimental basis for the application of ER fluids in the domain of structural vibration control.

Mr Effect

It is critically important to protect civil structures from unpredictable events, including earthquakes and strong winds, as well as maintaining their structural integrity and serviceability. To this end, considerable attention has been paid on the research and development of aseismic technology. This paper provides a literature review on the recent progress of Magnetorheological Elastomer (MRE) and the development and application of MRE devices on structure control technology. Firstly, this paper reviewed the investigations into the MR effect, mechanical property of MRE and its ingredients during the past decades. Then, research interests arising in the implementation and development of smart devices using MREs on structure control will be systematically reviewed. Basically, MRE base isolation and MRE based tuned mass damper are two major technologies to attenuate structural vibration, which will be the main focus of this paper.

Building shape coefficient is an important factor in building energy saving design. In order to analyze the influence of shape coefficient to the energy consumption, a typical residential building is simulated by BECS software to analyze the changing regular patterns of the energy consumption for heating and air conditioning while the building shape coefficient is made different. The relationship between building height and shape coefficient, and the impact of the building plane layout on the energy consumption are also analyzed. The results show that the reduction of shape coefficient is benefit to enhance the effect of energy saving.

The Impact

The hedge algebras theory has the potential to make significant applications in the field of computational intelligence. The purpose of the present study is to improve the control performance of the hedge algebras–based controller by tuning its control rules and apply the hedge algebras–based controller using the tuned rule base in vibration control of structures. The authors propose a “tuning coefficient” to express the impact of each rule of the controller in the control process. These control rules are adjusted by optimizing the above tuning coefficient. The tuned controller is then used to reduce the dynamic response of structures subjected to different excitations. The adjusted rule base is more appropriate for the model to be controlled, and it allows enhancing the control performance of the system. The proposed approach is uncomplicated and transparent, and it allows preserving the monotonous feature of the rule base.

Abstract Structural vibration control via passive electrical shunting and active (hybrid) actuation of a piezoceramic wafer bonded onto the surface of a simply supported beam is investigated with emphasis on modeling and understanding the effect of piezoceramic nonlinearity on system performance. A nonlinear rate-independent hysteresis model, the Maxwell resistive-capacitor (MRC) model, is experimentally identified for the PZT wafer by itself and then integrated into the coupled dynamic equations of the overall system consisting of the beam and electrically shunted PZT wafer. Experimental studies of the system validate the theoretical model. This model is then used to investigate the impact of PZT hysteresis on its vibration control performance in passive and hybrid scenarios that have been optimized based on a linear system assumption. A multi-term describing function representation of the MRC hysteresis model is formulated to aid in computational studies.

The Impact

Rotating scanning motor is the important component of synchronous scanning laser fuze. High emission overload environment in the conventional ammunition has a serious impact on the reliability of the motor. Based on the theory that the buffer pad can attenuate the impact stress wave, a new motor buffering Isolation Method is proposed. The dynamical model of the new buffering isolation structure is established by ANSYS infinite element analysis software to do the nonlinear impact dynamics simulation of rotating scanning motor. The effectiveness of Buffering Isolation using different materials is comparatively analyzed. Finally, the Macht hammer impact experiment is done, the results show that in the experience of the 70,000[Formula: see text]g impact acceleration, the new buffering Isolation method can reduce the impact load about 15 times, which can effectively alleviate the plastic deformation of rotational scanning motor and improve the reliability of synchronization scanning system. A new method and theoretical basis of anti-high overload research for Laser Fuze is presented.
