Abstract
I kesitli kirişin başlıklarında kayma gerilmesinin kalınlık doğrultusundaki bileşeni, elastisite teorisinin denge denklemlerinden biri kullanılarak hesaplanmıştır. Bu gerilmenin kalınlık doğrultusunda parabol şeklinde değiştiği ve ihmal edilebilecek kadar küçük olduğu belirlenmiştir. I kesitli kirişte gövde ve başlığın ortak bölgesi, kayma akımı için bir geçiş bölgesidir. İnce cidarlı açık tüp kesitteki kayma akımından faydalanarak bu bölge için basit bir hesaplama önerilmiştir. Buna bir örnek verilerek kayma gerilmesinin bu bölgedeki dağılışı açıklanmıştır.
The components of the shearing stresses along the thickness direction in the flange of an I beam are obtained by using one of the equations of equilibrium of elasticity theory. It is determined that this component varies parabolically along the thickness direction, and to be small enough to be neglected. The intersection area of the wall and the flange in the cross section of I beam is a transition zone for shear flow. For calculating of shear flow in this area a simple calculation is proposed by using shear flow of open thin walled beams. The distribution of shear stresses in this area is described by giving an example.
