Modeling seismic isolators, one of the most effective installations in design earthquake-resistant buildings, is a very important challenge. In this study, we propose new energy-based approach for optimization isolation parameters. The hysteretic energy represents dissipation isolated structures system. minimization input ensures that structural components are exposed to reduced energy. For these reasons, study aims minimize and maximize Additionally, an objective function also generated...

Free torsional vibration of cracked carbon nanotubes with elastic boundary conditions is studied. Eringen’s nonlocal elasticity theory used in the analysis. Two similar rotation functions are represented by two Fourier sine series. A coefficient matrix including springs and crack parameter derived using Stokes’ transformation conditions. This useful can be to obtain frequencies restrained calculated series compared finite element method analytical solutions available literature. The effects...

Being terrestrial for so many thousands of years, humanity is now advancing in the direction being extraterrestrial. Attempts made until were quite promising, like walking on Moon, living stations very long durations miles away from Earth, sending probes to unimaginable distances space and bringing them back etc. In coming decades, it easily predictable that man will spend time Moon lunar shelters periods which cannot be qualified as "short visits." This followed by going Mars other bodies....

This paper is concerned with the free vibration of cantilever microbeams attached tip mass in a systematical manner. Small size effects on vibrations microbeam are taken into consideration by introducing scale parameter. A Fourier sine series used to represent lateral displacement function. Stokes’ transformation applied present formulation and corresponding derivatives presented explicitly. The formulations can be readily reduced those for others classical elasticity models setting small...

It is obvious that lunar structures will be constructed on surface, and the materials to used are only soil. That why soils has investigated thoroughly as its physical, chemical mechanical properties. Unfortunately there not enough rock or soil brought Earth for being able run these analyses. For this purpose, several simulants have been produced in countries like US, Canada, Japan, China etc. This paper about an attempt carried out production of simulant Turkey. undegenerated samples...

Son dönemde, ülke kalkınmasının hızla artışı ile orantılı olarak dünyada olduğu gibi ülkemizde de birçok çevre sorunu yaşanmaktadır.Bu sorunlarından biri gürültü kirliliğidir.Karayolu trafiğinin birlikte öncelikle büyük şehirlerde meydana gelen kirliliği son dönemde küçük bir problem ortaya çıkmaktadır.Bilecik ili, göreceli il olsa da engebeli yapısı ve şehirlerarası yolu şehrin merkezinden geçmesi nedeni kirliliğinin ciddi boyutlara ulaştığı illerden biridir.Günümüzde birkaç tepeye yayılmış...

Advance of civilization has been realized through the ages by exploration unknown parts Earth and exploiting new resources thus acquired. There are currently practically no areas on this planet to be explored exploited. This is achieved completion period called globalization. As a natural continuation process, humans will now explore exploit beyond Earth, i.e. in space. Moon already partly, it awaits complete colonization. The next step Mars beyond. Habitation these space bodies firstly...

Bu çalışmada, karga arama algoritması (CSA) kullanılarak sismik izolatörlü bir yapının izolasyon parametrelerinin optimizasyonu

Ülkemizde, inşaat sektörü hızla büyümektedir. Şehir kenarlarına yapılan toplu konut projelerinin haricinde şehir merkezlerinde inşaatlar sürmektedir. Deprem tehlikesi karşısında yenilenen eski yapı stoku, bazı problemlere sebep olmaktadır. Bu problemlerin başlıcaları, trafik sıkışıklığı, yüksek tonajlı araçların sokak aralarında dolaşmaları, bina yapımı, yıkım tozları ve gürültüdür. çalışmada, temel inşaatı şantiye alanlarındaki gürültü kirliliği araştırılmıştır. Ölçüm için bir ölçer...

This study deals with the determining of slip resistance and classification potential for 5 different type Bilecik Beige Marble were applied tumbling. TS EN 14231 Standard "Determination Slip Resistance Pendulum Friction Test Equipment" was basically utilized in resistances wet dry surfaces. After tumbling process, by depending on reduce potential, especially conditions. values marble sample plates specified to be considerably change both surface processing techniques dry/wet...

In this study, we analyze housing energy consumption in Turkey. The is evaluated by using the multivariate techniques such as cluster analysis and multidimensional scaling (MDS) analysis. number of clusters for was selected five years. Finally, MDS results show that 2009 2010 most similar years consumption. paper present usefulness assessment

In recent years, many heuristic evolutionary optimization algorithms have been developed. Gravitational search algorithm (GSA) is one of these algorithms. It inspired by Newton’s law universal gravitation. this paper, we compare two modified based on GSA. One the called Member-Satellite algorithm. Members are randomly positioned in space and a certain amount satellites assigned around members predetermined region. their used to find near optimal solution all together. The second MSS-GSA....
