The utilization of fiber-reinforced polymer (FRP) reinforcements in structural design is increasing due to their non-corrosive nature. However, the anisotropic features and linear elastic behavior of FRP rebars have led researchers to explore the use of hybrid combinations of FRP and steel reinforcements. Current codes and guidelines predominantly...

Quasi-static experiments on columns and frame elements are of great importance in the study of earthquake behavior. One of the most important problems encountered during the experimental studies on the columns and frame elements under earthquake load was that the axial load on the columns could not be kept constant. The post-tensioning system used...

In recent years researchers are interested in using fiber reinforced polymer (FRP) bars as structural reinforcements due to their advantageous features, such as: resistance of corrosion and being lighter weight than steel bars. The high tensile strength of the FRP bars has allowed the use of them as tensile reinforcements, however; due to their ani...

Fiber-reinforced polymer (FRP) bars have been a promising alternative to conventional structural steel due to their compelling properties such as corrosion resistance, non-magnetic field formation, and low self-weight. The tensile strength of FRP reinforcements is higher than that of steel, which makes it possible to use them as tensile reinforceme...

Structural members under bending and axial compression may fail when the stress of the most critical fiber in the cross-section reaches allowable stress of the material or may fail due to buckling by deflecting laterally and twisting non-uniformly. This behavior is one of the most common stability problems named ‘Lateral Torsional Buckling’. In ord...

Building materials and structures keeping the functionality for many years without any deterioration is called durability. In this study, some experiments such as unit weight, ultrasonic pulse velocity, compressive strength, splitting tensile strength, and surface hardness tests are performed on concrete, partition wall brick and stone samples take...

If the earthquake damages are examined, it can be seen that structures which have overhangs are damaged more than the others. This fact creates a research interest in Turkey where 70–80% of buildings have overhangs. Although overhang direction and length must be designed by considering seismic loads and design rules are given in Turkish Earthquake...

The mechanical properties of structural reinforcement steel have been investigated after the exposure to high temperatures. Plain steel, reinforcing steel bars embedded into mortar and plain mortar specimens were prepared and exposed to 20, 100, 200, 300, 500, 800 and 950 °C temperature for 3 h individually. The S420 deformed steel bars with diamet...

Flat plate constructions are structural systems which are directly placed on columns without any beams. Various solution methods have been introduced for the solution of flat plate structures under horizontal and vertical loads. In most of these solution methods, models comprising of one column and one plate have been studied. In other solutions, h...

During recent years, researchers have focused their attention on the actual behaviour of beam-to-column joints. In general, structural analysis of frames are performed either for rigid joints or pin-ended connections. Nevertheless in practice, no joints are either fully rigid or actually pinned. A presumed rigid joint always allows for a relative r...
