Behaviour of Concrete-filled Double-skin Short Columns Under Compression Through Finite Element Modelling: SHS Outer and SHS Inner Tubes

M.F. Hassanein, M. Elchalakani, A. Karrech, V.I. Patel, more

Structures > 2018 > 14 > C > 358-375

Concrete-filled double-skin tubular (CFDST) columns are formed by sandwiching concrete between two concentric hollow steel tubes. The result is a composite column with the benefits of both steel and concrete properties. When compared to a traditional concrete-filled steel tube (consisting of a single hollow steel tube instead of two), CFDST column is found to have greater axial, flexural and torsional...

Shear analysis and design of high-strength steel corrugated web girders for bridge design

M.F. Hassanein, A.A. Elkawas, A.M. El Hadidy, Mohamed Elchalakani

Engineering Structures > 2017 > 146 > C > 18-33

Steel girders with corrugated web plates (BGCWs) have already been used in many bridges around the world because they own several advantages compared with traditional plate girders with flat webs. They have considerably high shear resistances and provide weight saving by reducing the web thickness and by eliminating the use of transversal stiffeners. However, these girders practically have been designed...

Experimental investigation of cementitious material-filled square thin-walled steel beams

M.F. Hassanein, O.F. Kharoob, M.H. Taman

Thin-Walled Structures > 2017 > 114 > C > 134-143

It was recently found that concrete-filled steel tubular (CFST) beams have some advantages in resisting forces compared to steel tubular beams. By using the CFST beams, the flexural capacity, stiffness, ductility and energy dissipation ability are improved due to the presence of the filled-in concrete. Currently, bending tests are performed on glass-fibre reinforced cementitious material-filled square...

Numerical investigation on the nonlinear shear behaviour of high-strength steel tapered corrugated web bridge girders

A.A. Elkawas, M.F. Hassanein, M.H. El-Boghdadi

Engineering Structures > 2017 > 134 > C > 358-375

Recently, there have been many attempts all over the world to reduce the own weight of the superstructure of the bridges, as well as reducing the work and cost involved in construction. One attempt is to utilise the tapered (i.e. non-prismatic with varying depth) steel plate girders with corrugated webs (TPGCWs). The corrugated steel plates are widely used as structural elements in many structural...

Plastic and yield slenderness limits for circular concrete filled tubes subjected to static pure bending

M. Elchalakani, A. Karrech, M.F. Hassanein, Bo Yang

Thin-Walled Structures > 2016 > 109 > C > 50-64

The current slenderness limits in international design codes are often based on certain rotation capacities obtained from plastic bending tests of Concrete Filled Tubes (CFT). In the past, a plastic slenderness limit of λ_s=188 was obtained by the first author based on a fracture rotation limit of the steel tube. However, such limit may be questionable being brittle and insufficient for plastic design...

Fundamental behaviour of concrete-filled pentagonal flange plate girders under shear

M.F. Hassanein

Thin-Walled Structures > 2015 > 95 > Complete > 221-230

Hollow tubular flange plate girders are found to possess higher flexural and shear strengths over those of I-section plate girders with flat flanges. Recently, concrete-filled pentagonal flange girders (CFPFGs) have been suggested in literature to increase the out-of-plane flexural strength of the girders. The geometrical configuration of the section is assumed identical to that of the girder with...
