摘要

The dynamic noise and vision protection wall has posts and panels or other surface components, with which the posts within its lower area has a moment reduction element (B) provided with springs and stopper. The wall inclines the posts with a relative switching of the spring constant of the springs and limited by the stopper on a definite angular area. The dynamic load is counterpart by a profound tuning.
