Optimization techniques may be effective in finding alternative design of post-tensioned
slabs to improve their mechanical behaviour, particularly reducing the bending moments …

Optimum design of post-tensioned flat slabs with its columns is complicated by the presence
of many nonlinear constraints and the non-homogeneous nature of the material used. This …

The present research is focused on developing efficient, durable flexural members by
combining the use of lightweight concrete (LWC), fiber‐reinforced polymer (FRP) bars, and …

In this study, a post-tensioning method using externally unbonded steel rods was applied to
pre-damaged reinforced concrete beams for flexural strengthening. Nine simply-supported …

The present study examined the flexural behavior of externally post-tensioned lightweight
aggregate concrete (LWAC) beams under symmetrical top one-point, two third-point, and …

The development of lightweight aggregate concrete (LWAC) has brought new design
opportunities. The high strength and simultaneous low densities can lead to economically …

To investigate the mechanical performance of prestressed lightweight aggregate concrete
hollow slabs, a symmetric loading test was performed on eight prestressed concrete hollow …

Existing design guidelines, codes, and literature provide different calculation models for the
estimation of tendon stresses in unbonded posttensioned concrete members at the ultimate …

Prestressed concrete bridges with corrugated steel webs have emerged as one of the
promising bridge forms. However, the presence of prestressing tendons and shear …

Optimization in its wide sense can be used to solve many engineering problems and to find
the best solutions so that designers can gain a maximum benefit from the available …
