This paper presents a physics-based approach to obtain 2D or 3D dynamic pedobarography transitional objects from two given images (2D or 3D). With the used methodology, we match nodes of the input objects by using modal matching, improved with optimization techniques, and solve the Lagrangian dynamic equilibrium equation to obtain the intermediate shapes. The strain energy involved can also be ...

A vibration based damage identification method is investigated experimentally. The dynamic response of an intact and a locally damaged 16–layer unidirectional carbon fibre PEKK reinforced plate structure with two stiffener sections is considered. A forced–vibration set–up, including a laser vibrometer system, is employed to measure the dynamic behaviour. The feasibility of the two–dimensional M...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

the useful and efficient method of finite element (fem) has a drawback for dynamic analysis of complex structures, especially in the medium and high frequency range. to overcome this fundamental difficulty, application of statistical energy analysis (sea) and power flow technique has been suggested. as the sea is based on the average response of structure and statistical properties of its reson...

Life cycle monitoring of civil infrastructure such as bridges and buildings is critical to the long-term operational cost and safety of aging structures. Nevertheless, there is no commonly accepted and recognized way to perform automated monitoring of bridges. One of the important issues is the cost of the data acquisition subsystem and its installation and maintenance costs, which are tightly ...
