Calcium carbide gas pressure (CCGP) method is a rapid measurement procedure for obtaining soil water content (SWC), which relies on the chemical reaction of the calcium carbide reagent with the water in soil pores. Currently, ...

In this paper a time varying optimal control algorithm (β-Method) is proposed to control building responses, against environmental earthquake excitations. The proposed method is presented through defining a rational relation ...

In this paper, an elastoplastic model is proposed to analyze the circular tunnels below the groundwater table under axial-symmetric condition, considering the effects of seepage and gravitational loads. In the proposed ...

Changes in the dynamic properties of structures indicate an occurrence of damages in them. In this paper, the dynamic properties of damaged structures under diff erent scenarios are obtained using suitable nite element ...

Using the concept of strain energy change, due to damage at the element level, a new structural damage detection method is developed. The proposed method employs either static or dynamic response of a structure and ...

Semi-active devices are low-cost as well as small and by changing the properties of low-power intensive structures, the aims of control are accomplished. On the other hand, the limited control force which can be applied ...

To identify structural damages many different methods have already been developed. Evaluating the performance of these methods is not a convenient task because they have been applied to different structures or constructed ...

This paper presents a review of recent advances made in vibration-based Structural Health Monitoring (SHM), using the responses of the structure to an excitation. The review is divided into parameter and feature estimation, ...

Many industrial problems are concerned with optimization of large and complex systems involving many criteria. Indeed, optimization problems encountered in practice are seldom mono-objective. In general, there are many ...
