The aim of this paper is to present results of testing a full scale reinforced concrete T connection by static loading. The connection represents a beam-column connection. The beam and column had a square cross section with a 300 mm dimension. The height of the column was 2.9 m and the clear beam length was 1.4 m. The connection was initially tested to failure. Galvanised steel straps were used...

Slotted waveguides are often used when high-power and high-efficiency antennas must be designed particularly for millimeter waves applications (automotive radar example). But it is not easy to choose any distance between radiation slots because of the guided wavelength, obtain a wide beam in E plane so cover angular sector scanning antennas. Moreover, main depends frequency progressive wave ant...

In this paper, a theoretical model based on the electric field integration method is proposed to analyse radiation properties of slotted annular Leaky-Wave Antenna (LWA), which can generate Circularly Polarized (CP) conical beam or broadside beam. The LWA contains radiating elements arranged along circular travelling-wave structure with equal intervals. By combining and theory, design procedure...

The paper reports the results of a collapse test performed on a 6 m span timber-concrete composite beam with glued re-bar connection. The beam was first ramp loaded to failure, then some push-out tests were performed on specimens cut from the end of the beam in order to fully characterise the connection. During the tests all relevant quantities such as deflections, slips and strains were monito...

The slotted-hidden-gap (SHG) connection eliminates the need to reinforce slot region of hollow structural sections (HSS) braces concentrically braced frames (CBFs). However, existing design approach for SHG connections is rather empirical and limited by range geometries materials that had previously been tested. A general based on findings a large-scale parametric study presented in this paper,...

Since the earthquakes in Northridge and Kobe in 1994 and 1995, respectively, many investigations have been carried out towards improving the strength and ductility of steel beam to column pre- and post-Northridge connections. In order to achieve these objectives, recent researches are mainly focused on three principles: reducing the beam section to improve the beam ductility, adding different k...

Steel extended end plate bolted connections are recommended to be widely utilized in special moment-resisting frame subjected to monotonic loading. Improper design of steel beam to column connection can lead to the collapse and fatality of structures. Therefore comprehensive research studies of beam to column connection design should be carried out. Also the performance and effect of corrugated...
