1 Introduction As in most design codes, in cases where members do not require design shear reinforcement, the expression of the design value for the shear resistance given by Eurocode 2 is based on experimental investigations. Although the

We have investigated effects of shear flow on the structure of lamellar phase in hepta(oxyethylene glycol)—n—hexadecylether—water system using small-angle neutron scattering (SANS) under shear flow at the shear rates (
=10–2 ~1 s–1, significant changes have been observed in both intensity and position of the reflection peak. Small-angle X-ray scattering without shear has been also measured at various concentrations and temperatures. It has been suggested from these results that the shear flow causes contraction of lamellar domains and formation of a new domain composed of disrupted bilayers which grows rapidly with increasing shear rate and reconstructs original microstructures.

Knowledge of shear strength along discontinuities in rock mass is essential for the design process of underground structures, such as tunnels ( Borbély et al. 2015 ), foundations, and rock slope stability
The resistance of steel-concrete composite trusses is significantly influenced by shear connection producing interaction between the steel beam and concrete slab. To create the interaction between these structural parts, it is needed to prevent the relative slip at the steel-concrete interface using the shear connectors. Push-out testing can reflect the more real effect of the longitudinal force and reproduce the distribution of the shear force between the steel section and concrete slab. The finite element analysis is used in the paper to investigate numerically this structural system behavior, exploiting finite element computer procedures.
Several types of economical and effective connectors are commonly used
for composite steel and concrete beams at present. Perforated shear connector
has been developed during last two decades and have become popular due to their
advantageous properties. At the Department of Steel and Timber Structures of
CTU many experiments (push-out test) were carried out with two types of
connector with different openings, various strengths of concrete and amount of
reinforcement. The design formulas for static shear load capacity were deduced
on the basis of these experiments. Nowadays, small modification of basic
connector was designed for decrease of laboriousness in situ. Results of
modified connector are in good compare with previous one.
