Reliability Analysis of Carbon Fiber Reinforced Polymer (CFRP) Strengthened Steel Beams
… techniques used to produce the joints. Reliability analysis of adhesively bonded CFRP-to-steel double-lap shear (DLS) joints with thin outer adherends was performed first, to study the bond behavior when dominated by adhesive shear stresses. A comprehensive experimental database of the …

Reliability-Based Topology Optimization with Analytic Sensitivities
… it may have a design which is too conservative. Reliability-Based Design Optimization (RBDO) is an alternative approach which directly considers the likelihood of failure by incorporating a reliability analysis step such as the First-Order Reliability Method (FORM). The FORM analysis requires the …

An effective optimisation method for multifactor and reliability-related structural design problems
This thesis first presents a systematic design procedure which satisfies the required strength and stiffness, and structural mass for conceptual engineering structural designs. The procedure employs a multi-objective and multi-disciplinary (MO–MD) optimisation method (multifactor optimisation of …

Reliability analysis of green roofs under different storm scenarios
… area. Green infrastructure offers an alternative method of runoff reduction, by using natural processes to infiltrate, store, and treat runoff at its source. In particular, green roofs can promise multiple benefits in terms of runoff reduction, air quality improvement, and mitigation of the urban …

Performance-based earthquake engineering with the first-order reliability method
Performance-based earthquake engineering is an emerging field of study that complements the prescriptive methods that the design codes provide to ensure adequate seismic performance of structures. Accounting for uncertainties in the performance assessments forms an important component in this area. …
