In the presented paper is comprehensively assessed the behavior of spruce and birch wood during fire. Samples were loaded by heat flux of 20, 35 and 50 kW/m2 in apparatus according to ISO 5657. The duration of the test was up to 30 min. The behavior of the samples was evaluated on the basis of charring rate and concentrations of carbon monoxide in smoke. Charring rate was rising with increasing heat flux density and decreasing linearly with increasing density of the samples. The maximum concentration of CO in the smoke for spruce and birch wood was observed just before the end of the test, during the phase of char layer burning.

This paper presents the results of static tests of round timber bolted joints with inserted steel plates. All round timber joints static tests in tension were carried out on pressure machine EU 100 in laboratory of the Faculty of Civil Engineering VŠB-TU Ostrava. At first, timber specimens were tested without reinforcement. Based on these results, mechanical reinforcement methods were proposed: using modified washers and boost with screws. These samples were also tested. Rate of improvement in tensile strength was established for used reinforcement method.

The aim of this article is in description of behavior and bearing capacity of one-shear nail joints in joints of cement-splinter boards with middle solid wood element on the base of destructive laboratory testing according to valid European standards [1]. The second part of this paper describes typical damage of these joints and comparison of these results with bearing capacity of the same way arranged and loaded joints, where however instead of cement-splinter board solid wood boards were used.

The aim of this paper is determination of embedment strength of cement-splinter boards in dowel dual-shear joints on the base of destructive laboratory measurements of these joints with selected diameters. Reliance of embedment strength on dowel diameter is determined.

The aim of this paper is determination of selected strength characteristics of dowel joints in cement-splinter boards VELOX on the basis of destructive testing and application of these results into the fully probabilistic SBRA method (Simulation Based Reliability Assessment).
