The reinforcement strain,crack width,crack width-load and reinforcement stress-load relationship at various load levels are measured and the development of crack is monitored.

Analysis and test of steel stress of concrete beam during curing period;

In this paper,the steel stressof a special skew frame structure i5 studied with measuringmethod in situ.

An engineering case is taken as an example to analyze all factors and extents affecting the large calculating stress of steel bar stress in foundation slab in detail.

Analysis on testing data of deep horizontal displacementand steel bar stress of soil-nailing support work demonstrates that thehorizontal displacement of foundation pit increases with the extension ofconstruction time, and the maximum tension is associated with potentialsliding tendency of side slope while the end of soil-nail at lower row insoft soil foundation bears heavier load.

Based on filed measured date and calculated result about the internal force of the anchor piles retaining structure in Handan,the reinforcement stresses and moments of the piles along with the excavation of the deep pit are studied in this paper.
