- Kurzbeschreibung<p>Project Report from the year 2015 in the subject Engineering - Civil Engineering, grade: 1.3 (90-100%), Dresden Technical University, language: English, abstract: In the frame of a research program at the TU Dresden, reinforced concrete slabs are tested in a drop-tower. The goal is to obtain a model with which the prediction of the structural behav-ior of the slabs under high loading rates, depending on different parameters. <br>The global behavior response of RC slabs (symmetric reinforcement without shear stirrups) due to a hard impact projectile and a strain rate 10-1 [1/s] has been addressed in this project-work. <br>A complex drop-mass apparatus is used to conduct experiments and investigations on the impact dynamic behavior of RC slabs<br>The focus was on the response stage of the linear elastic field and how to correlate this re-sponse stage to the drop-height depending on raw experimental data.<br>A process of data analysis for hundreds, thousands, or millions of data measurements has been carried out and an analytical model based on a system of single degree of freedom and different simplifications is shown with different verification methods. The model enables predicting bending response due to impact.<br>The test of 11 slabs with drop-heights (1 to 4 meters) provides the required data to calibrate the analytical model as well as future numerical models.</p>
