“…The applied load induces crystal phase transformation that is reversed when the load is removed. Devices made from SMA are therefore self-centring 12,13 . The desirable features of these devices are stable hysteretic behaviour, low-cycle fatigue property, longterm reliability, and relative insensitivity to environmental temperature variations.…”

Structures constructed in developing world are typically RC frames with masonry infill. These structures have little resistance for lateral loads caused by earthquake and wind. Even for adequately designed structures also, due to permissible deformation beyond elastic limits, failure of masonry causes severe loss of life and property. In the case of structures designed to sustain excessive deformation such as of defence establishments, functioning and serviceability of machines and equipment installed therein are adversely affected. This co-lateral damage may be reduced by adopting another design philosophy of structure response control. In this methodology, a supplementary damping device is incorporated in the primary structure, which absorbs most of the seismic energy imparted to it, restricting the structural response within serviceable limits. These devices may be passive, active, semi-active or hybrid types. Other than passive all options are technology-intensive and dependent on external energy source, not a favourable proposition for developing nations. Among all the passive devices, tuned liquid dampers (TLDs) promise to be most suitable. Here, existing overhead water tanks (OHWT) may be used as TLD with slight adjustment and modification. This method will be able to control the structural response without putting any extra load on the existing or newly-designed buildings. This paper reviews various types of dampers and discusses evolution of tuned liquid dampers. A method has also been proposed for incorporating TLDs in existing and new structures. This methodology may be very useful for structures of defence establishment which are scattered and remotely placed by location, housing important equipments sensitive to vibrations, as it is free from external power dependence and regular maintenance.

“…Their behavior has been studied analytically and experimentally. Aiken et al [2,3] discussed a friction damper mounted on K-bracing. When the structure excites, relative movement between the structure and the brace drives a copper alloy friction pad as it slides along the inner surface of a cylinder's steel casing.…”

“…Fitzgerald et al [5] proposed a friction damper that utilizes slotted bolted connections in concentrically braced frames. Extensive studies have been conducted on friction dampers,which has led to their practical application for structural seismic protection [2,6]. Mualla [7] innovated a Friction Damper Device (FDD), based on friction between steel plates and friction pad made from special material.…”

“…Structural control using passive dampers is becoming a popular and promising strategy in the structural design of infrastructures in earthquake-prone countries where earthquake resilience and continuing use of buildings are strongly desired (Hanson, 1993;Aiken et al, 1993;Nakashima et al, 1996;Soong and Dargush, 1997;Hanson and Soong, 2001;Takewaki, 2009;Lagaros et al, 2013). In the 2016 Kumamoto earthquake in Japan, severe shaking over the Japan Metheorological Agency (JMA) seismic intensity six was repeated during a short time span and the control of responses within a limited plastic deformation is strongly desired.…”

A closed-form maximum elastic-plastic response is derived for a structure with hysteretic dampers under the critical double impulse as a representative of near-fault ground motion. It is shown that the classification into nine cases is possible depending on the combination of elastic-plastic responses of the structure and the hysteretic damper and the double impulse enables the derivation of the closed-form maximum elastic-plastic critical response of the controlled structure by using the energy balance in each case. It is demonstrated that the closed-form maximum elastic-plastic critical response is quite useful for finding an optimal hysteretic damper quantity depending on the input level of the double impulse.
