Numerical Modelling of Time-Dependent Behaviour of Reinforced Concrete Structure with Use of B3 Model

Abstract

The paper proposes an implementation of creep analysis of reinforced concrete structures which utilizes the B3 model and the direct stiffness method for reinforced concrete frames. The analysis is based on a numerical integration and it is implemented in an algorithmic programming language. There is presented a solution with the mentioned approaches which is compared with solution based on the EN 1992-1-1 technical standard.

Determination of Concrete Cube Strength from Used Samples / Určení Krychelné Pevnosti Betonu U Použitých Zkušebních Trámců

Abstract

This paper deals with the determination of compressive strength of concrete. Cubes, cylinders and re-used test beams were tested. The concrete beams were first subjected to three-point or fourpoint bending tests and then used for determination of the compressive strength of concrete. Some concrete beams were reinforced, while others had no reinforcement. Accuracy of the experiments and calculations was verified in a non-linear analysis.

NUMERICAL ANALYSIS OF CASTELLATED BEAM

Abstract

This paper deals with modeling of the behavior of castellated beam. The calculations also take into account the imperfections. The solution incorporates finite element models and standardized calculation. The main contribution is to undertake case studies to determine the coefficients of lateraltorsional buckling and description of the stress state of the profile

Experimental and Numerical Analysis of Steel Joints in Round Wood

Abstract

The paper analyses a drawn steel joint in round logs for which several types of reinforcements have been proposed. The load-carrying capacity of the reinforcements have been tested in laboratories. At the same time, numerical modelling has been performed - it has focused, in particular, on rigidity of the joints during the loading process. Physical and geometrical nonlinearities have been taken into account. The Finite Element Method and 3D computation models have been used in the numerical calculations.
