This paper provides an experimental analysis of timber-framed walls, coated with single fibre-plaster coating boards fastened to a timber frame. As the walls under a horizontal load actually behave like a deep composite beam, a fasteners disposition is very important and directly influences bearing capacity as well as stiffness of a wall. The presentation, based on the measured results, ascertains that fastenersć spacing has a remarkable influence on behaviour of the treated walls in many aspects.

The paper presents the outcomes of a research and development project, which introduced a building information model (BIM) and a model based construction process into the operational environment of a construction company. The initiative for the project came from the industry. Work was performed in the scope of an industrialized construction environment, with the main aim to integrate mass production prefabrication processes with construction site activities. The benefits of this link are presented with regard to project progress monitoring and material flow management.

The paper presents the simultaneous cost, topology and standard cross-section optimization of single-storey industrial steel building structures. The considered structures are consisted from main portal frames, connected with purlins. The optimization is performed by the Mixed-Integer Non-linear Programming approach, MINLP. Internal forces and deflections are calculated by the elastic first-order constraints, the dimensioning in accordance with Eurocode 3. A numerical example of the cost optimization of a single-storey industrial steel building is presented at the end of the paper.

This paper presents a new geometrical stiffness matrix for a transversely cracked beam-column with linear distribution of axial compressive force. This matrix can be utilized in a beam finite element model of the structure for analyzing ultimate buckling load, according to the Euler's elastic flexural buckling theory. The newly presented matrix and stiffness matrix for analysis of transverse displacements, present an efficient tool not only for buckling analysis of cracked beam structures but also for a better description of the structure regarding the inverse identification of cracks.

This paper formulates the finite element of a beam with an arbitrary number of transverse cracks. The derivations are based on a simplified computational model, where each crack is replaced by a corresponding linear rotational spring, connecting two adjacent elastic parts. The stiffness and geometrical stiffness matrices thus take into account the effect of flexural bending deformation caused by the presence of the cracks. This element could be efficiently implemented also in inverse identification of cracks in beam-like structures.
