Webb10 apr. 2024 · Cracking is one of the main diseases of small- and medium-span reinforced concrete (RC) bridges. It is a key problem to determine the change in mechanical properties of RC beams after cracking in bridge-performance evaluation. The present study performs static loading tests on seven simply supported T-beams with different crack damage … WebbCollect experimental data and create a solubility curve. By the end of this lab, students should be able to: Properly use an analytical balance to measure mass. Set up an …
