This study presents three design optimization algorithms where the design provisions are implemented in accordance with ACI 318-11. Design variables are divided into two groups. The first group of variables refers to post-tension slab including the thickness of slab, number of tendons and their ...
The use of higher strength concretes and steel yield strengths allows designers to design thinner slab systems which satisfy all the requirements of strength. However, the use of thinner slabs leads to increased deflections and the possibility of violating deflection serviceability criteria. The shore-...
Punching shear behaviour of the Column-slab connection using the normal reinforced concrete is usually sudden brittle failure due to the stress concentration at the small area surrounding the column. Thus, continuous research effort is performed to validate the current design recommendations available by ...
The method is compatible with the equivalent frame method of the ACI Building Code (ACI 318-71) and is an extension of the work related to elastic deflections of slab systems. Available experimental data in the literature is compared with the estimates provided by the procedure and found to ...
Punching is a critical design case for reinforced concrete flat slabs but the provisions for punching shear design and detailing of the shear reinforcement differ considerably among the various European and American design codes. Therefore the thickness of the slab or the amount or distribution of sh...

In structural design practice, however, punching shear is often eccentric, due to the asymmetry of spans and loading. The transference of unbalanced moments in the slab-column connections reduces the punching resistance and ACI 318 [23] and Eurocode 2 [24] assume that this reduction can be comp...

Scaled models have been used in an experimental investigation of the punching capacity and moment transfer characteristics of typical flat slab edge column connections. One of the main aims was to examine the influence of, and attempt to relate, the location of the slab free edge to the column...
The ability of a flat slab to resist punching depends on various parameters: including slab thickness, column dimensions, fcu, different types of shear reinforcement, and other factors that remain subjects of ongoing research [6]. Design codes employ diverse methods and consider different parameters ...
