They cause larger stresses in structural members than those produced by gradually applied loads of the same magnitude.

WebIn that case, the unit stress at any point in the section is the limiting value of the ratio of the internal force on any small area to that area, as the area is taken smaller and smaller. Sometimes in the design of a structure, unit stress may not be the prime consideration. WebA stable structure resists loads and stays in place with minimal deflection. An unstable structure fails, not from structural members failing due to over-stress, but from the unsoundness of the geometry and the connection types. The figure below illustrates. Many times temporary structures are built on a job site that are unstable and dangerous.
