Disadvantages of Frames: 1.

n frames frames structure structures! s! span lengths lengths are are usually usually limited limited "hen normal normal reinforce reinforced d concrete concrete #generally less than about 13 m! but up to about 1$ m%. Other"ise spans greater than that! can cause lateral deflections.

2. &enerally! frames are are fle'ible structures and lateral lateral deflections deflections control the design design process process for for  buildings "ith greater than about about 4 stories.

 Advantages of Structural Structural Walls 1. Load bearing bearing walls reduce interstor interstorey ey distortions distortions due to to earthquake-induced earthquake-induced motions and reduce the likelihood likelihood of damage to the nonstructural nonstructural element s of building. 2. Buildings stiened by structural structural walls during during earthquak earthquakes es have pointed pointed to be be consistently better performance than rigid-framed buildings. . !he performance performance of buildings buildings stiened stiened by properly design structural structural walls walls has been better with respect to both safety and damage control. control. ". # structure structure with structural structural walls$ walls$ which which is substantially substantially stier and hence has a shorter period than a structure structure with frames$ will suer less lateral displacement than the frame$ when sub%ected to the same ground motion intensity. &. !hey are are used to keep the the lateral drift within within reasonable reasonable limits limits by resisting resisting hori'ontal forces.
