in this paper, buckling of simply supported column with an edge crack is investigated numerically and analytically. four different scenarios of damage severities are applied to a column, open crack assumption and the effect of closing crack in stability of the column which depends on position and size of cracks, are numerically compared. crack surfaces contact is modeled with gap element using ...

in this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. the bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. a total number of one hundred and two (102) sensors are...

Wheelchairs, trolley chairs, and potty chairs are essential for people with disabilities, patients, elderly. These forms of equipments specially designed to support specific needs their users, such as moving, bathing, resting, etc. Since the function equipment is limitted, patients multiple problems may need more than one single be properly supported, which make caring processes complicated bec...

Türk Bina Deprem Yönetmeli?i-2018’de (TBDY-2018) tan?mlanan ve dü?ey do?rultuda düzensizlik durumlar?ndan biri olan kom?u katlar aras? rijitlik düzensizli?i (yumu?ak kat), özellikle zemin katlar? ticari amaçlar nedeniyle üst katlardan farkl? tasarlanan mevcut betonarme binalarda yayg?n olarak görülmektedir.

Earthquakes are one of the most vulnerable disasters that effected many countries including India. Due to continuous ground motions caused by an earthquake structure gets damaged or even collapses causing human loss, property loss and psychological fear among humans. Many techniques available resist from seismic loads like base isolation devices, dampers, shear walls, outrigger structure, brace...

In China, conventional island shield buildings (CISBs), which are situated close to the nuclear islands of power plants, class III seismic items. This is most important level in fortification standard. Calculations check resistance overturning under extremely safe action should be carried out. Although strict design has been out, many beyond-design-basis events, such as 3/11 earthquake Japan, h...

The safety assessment of existing structures in areas with a relevant seismic hazard is one the major topics for engineers since many reinforced concrete have been realized disregarding design minimal details respect to present practice. In this context, primary issue order identify best retrofitting solution aim enhancing efficiency buildings. recent years, enhance behavior (RC) (with particul...

Saplama/ikincil kirişler, uçlarından kolon, perde veya kirişlerle mesnetlenmemiş kirişlerdir. Kirişlerin kolonlarla desteklenmemesi durumunda, kiriş yükleri başka kirişlere aktarılarak bir ifade ile ikincil kirişler oluşturularak yükler dolaylı yollardan düşey taşıyıcı elemanlara aktarılmış olur. Bu durum, kirişleri taşıyan çerçeve kirişte kesme ve moment artışı birlikte, ilave burulma momentle...
