Abstract Geotechnical seismic isolation has emerged as an efficient technique for mitigating the severe effects of earthquakes by providing smooth synthetic liners beneath foundations or between soil layers dissipating energy through sliding. This study investigates efficacy using a rubber mat and natural coir reinforcement materials within to act soil-isolation medium. A three-dimensional fini...

Abstract Indonesia is located at the confluence of three main tectonic plates which makes it one countries with highest earthquake risk in world. Recorded experiences has showed that cause damage to buildings particularly multi-storey building structures. The purpose this study determine performance level reinforced concrete structures using a performance-based design method based on ATC-40 and...

response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...

This paper looks at parking policy in dense urban districts (“downtown”), where spatial competition between parking garages is a key feature. The paper has four parts. The first looks at the “parking garage operator’s problem”. The second derives the equilibrium in the parking garage market when there is no on-street parking, compares the equilibrium to the social optimum, and examines parking ...

This paper recognises that comparisons have been made between the role of the conductor of an orchestra and leaders of enterprises, but that little note has been taken of how the complex dynamics of orchestras can provide metaphors for transformational and / or evolutionary behaviour in complex enterprises. The paper intends to identify some of the dynamic musical patterns and phenomena that ex...

Mobile olfactory robots can be used in a number of relevant application areas where a better understanding of a gas distribution is needed, such as environmental monitoring and safety and security related fields. In this paper we present a method to integrate the classification of odours together with gas distribution mapping. The resulting odour map is then correlated with the spatial informat...

Using a small number of ERS InSAR images from 1996-2003 we have shown that deformation is occurring in Rotorua in a region located on the margin of the active thermal area. Subsidence in the area south of Kuirau Park at rates of up to 13mm/year during 1996 to 2000 are indicated, although the linearity of the deformation has not yet been confirmed. The Envisat data, available from 2003 onwards, ...

Background: A field study on the transfer of primordial radionuclides 238U, 232Th, 40K and fallout radionuclides 210Po in different plant species in tropical forest of western Ghats environment is presented. Material and Methods: The Top storey, Second storey, Shrubs and epiphytic plant species were chosen and concentration of these radionuclides in plant and soil were measured by employing gam...

The primary objective is to present the most representative types of damage observed in reinforced concrete (RC) structures due earthquakes. Those damages are divided according ten types. Examples and main reasons that could trigger each failure mechanism presented. definition these supported by post-earthquake reconnaissance missions Sichuan (China) 2008, L’Aquila (Italy) 2009, Lorca (Spain) 2...

in this work, we define fuzzy soft ($fs$) matrices and theiroperations which are more functional to make theoretical studies inthe $fs$-set theory. we then define products of $fs$-matrices andstudy their properties. we finally construct a $fs$-$max$-$min$decision making method which can be successfully applied to theproblems that contain uncertainties.
