![]() This causes the joint to rotate by a small amount which is opposite to the case in a rigid joint. A pin joint transfers horizontal and vertical loads and cannot resist any rotations moment. The connection formed by pin joints does not transfer moments. In braced frame structures, pinned joints are used to connect beams and columns. Beams and columns primarily carry vertical loads and bracing resists lateral loads. A braced frame essentially consists of an assembly of beams and columns with a bracing system in between the members. Tall structures are one of the most common examples of structures that are exposed to strong lateral forces.ĭepending on the situation, we have to introduce certain mechanisms in a building that will enhance its resistance against lateral loads.īraced frame is one of the commonly used mechanism in this regard.Īlso Read: Load Bearing Structure – Types, advantages Vs Frame Structure What is a braced frame?Ī braced frame is a structural system used in structures that are subject to lateral forces primarily due to wind and earthquake.īracing, in particular, is a secondary arrangement provided in structures to resist lateral loads. This specifically becomes significant in high rise buildings where lateral forces are the most important design consideration. Structures located in seismic zones where earthquakes are common fall under this category. Primary lateral forces that a structure may experience are wind loads and earthquake loads.Īlso Read: Types of Building Structure in Civil Engineering with images Not all structures are required to be designed to resist lateral forces. There are situations when we have to design a structure in such a way that it can safely accommodate lateral forces that it may experience during its life. So, in our today’s article we’re going to elaborate some important aspects of braced frame structures. You can easily use brace frames for its flexibility, strength, and stiffness. It includes steel bracing that is easy to erect and can resist more forces than non-braced buildings. In different types of frame structures, braced frame are ideal to resist lateral forces like wind and earthquake loading.
