STUDI KASUS SENSITIVITAS RESPON STRUKTUR TERHADAP ARAH DATANG ANGIN

CASE STUDIES OF THE SENSITIVITY OF STRUCTURAL RESPONSES TO WIND DIRECTION

ABSTRAK

Orientasi stuktur terhadap arah datang angin adalah hal yang perlu diperhitungkan untuk mendesain layout bangunan. Pada beberapa kasus rencana tapak telah ditentukan sebelumnya oleh para arsitek biasanya penentuan tersebut mengutamakan estetis bangunan dan tata kota. Jika penentuan tapak bangunan tidak diperhitungkan secara menyeluruh dan ketika angin berhembus kuat pada arah tertentu hal tersebut akan menyebabkan kegagalan pada struktur. Riset ini menyajikan sensitivitas respon struktur terhadap arah datang angin dan mengambil studi kasus pada bangunan berbentuk segi empat CAARC Standard Tall Building dan mengambil data kecepatan angin di Taipei. Respon momen tekuk dari data wind tunnel dapat ditransformasikan menjadi respons struktur seperti percepatan pada puncak gedung dan interstory bangunan untuk arah x dan y. Respon struktur bergantung pada performa dari bangunan itu sendiri. Respon struktur dapat menjadi sangat sensitive terhadap orientasi struktur karena kecepatan angin yang tinggi pada arah tertentu dan ketika layoutorientasi struktur sedikit dirotasi akan dapat mengurangi atau bahkan menambah performa dari struktur.


ABSTRACT

Structure orientation toward the wind direction is the most critical problem to be considered. In some cases site design has been initially determined due to the plan area or the urban artistic and if the wind blow in a strong directionality that would become a failure for the building. This research presents the sensitivity of the structural orientation and takes the case study of CAARC Building located on Taipei. Response base moment from wind tunnel test data in a function of natural wind direction angle could be transformed into structural responses such as top story acceleration and displacement for x and y axis component. The structural response depends on the building performance. The structure response could be very sensitive to the structural orientation. Besides that it also describes the effect when structural orientation changed a bit it would decrease or increase the effect of building.
