Automated Engineering Design for Reusable Concrete Building Structures
Published 2024“…The Pixelframe structural system [1] was proposed to facilitate the reusability of concrete components by implementing the existing external post-tensioning system in bridge structures and fiber reinforced system to design building beams and columns. This work presents an automated engineering design workflow for Pixelframe, including a engineering mechanics of the system that conforms to ACI 318- 19 [2] and fib Model Code 2010 [3], half-scale tests to verify the preliminary behavior of the system, and a scalable design algorithm for minimum embodied carbon designs. …”

Impact of structural eurocodes on steel and composite structures
Published 2014“…In this connection, this paper investigates five key design aspects comprising material properties, flexural buckling resistance of compression members with Grade S460 steel, shear buckling resistance of plated structures, web bearing and buckling resistance of the plated structures under transverse force and lateral-torsional buckling of composite beam. It is found that the flexural buckling resistance, web bearing and buckling resistance and lateral-torsional buckling resistance determined from Eurocodes 3 and 4 are much larger than those from BS5950. …”
