An equivalent definition of the dyne is "that force which, acting for one second, … WebThis is where post-tensioning comes in. PT systems provide active reinforcement. The function of post-tensioning is to place the concrete structure under compression in those regions where load causes tensile stress. Post-tensioning applies a compressive stress on the material, which offsets the tensile stress the concrete might face under loading.
WebPost-tensioning tendons, which give the pre-tension of the steel ropes inside the channels and sleeves, are placed in the area before the concrete is placed. Then, once the concrete has strengthened, the ropes are tightly pulled or stretched and abutted against the outer edges of the concrete before the load is applied.
