Two concrete mixes were investigated (C30 and C80). The specimens are named with the concrete type followed by a roman number (e.g. C30-II). The specimens were loaded with a sinusoidal load, oscillating between a relative minimum and a maximum load level. The minimum load level was aimed to be 5% of the compressive strength and the maximum load level 75%. An exception was beam C80-VI. A maximum load level of 65 % was chosen here. Each beam was from a different concrete batch and for determining the compressive strength of the respective concrete batch, three cyclindrical specimens were cast together with each beam. Before starting the beam test, the compressive strength was determined on the cylindrical specimens. In a first step, the beams were prestressed. Afterwards a vertical prestressing was applied to achieve a mean loading in the specimens. In the third step, the fatigue test was started. The Layout of all sensors is provided in a separate file here. The data of the sensors can be found in .ASC files.

It involves prediction and parsing scores monitored during the training of each classifier and extracted set of supertags in the grid searches for viable extraction hyperparameters. A table provides an overview of the final model scores for each treebank. 2024-01-01T00:00:00Z https://opara.zih.tu-dresden.de/xmlui/handle/123456789/6122 disutapa Ruprecht, Thomas This project is an implementation of the supertagging-based parser for discontinuous constituent trees as described in my phd thesis "On the Extraction of Lexicalized Grammars and Parsing via Supertagging for Discontinuous Constituent Structures."

The first part contains the results of cyclic 4-point bending tests on cuboid specimens. They were used to measure the residual stress. Each specimen was loaded with a certain number of load cycles, after which the test was stopped and the residual stress was measured. From this, the development of the residual stresses under the cyclic load can be determined. The second part of the data set contains data from characterization tests. Various uniaxial tests were carried out on a material sample in order to obtain information for the parameterization of numerical models for predicting the development of residual stresses from the first part of this contribution. 2024-01-01T00:00:00Z
