Abstract. Dividing walls are usually considered as non-structural elements,

but experiences of past earthquakes show that some buildings designed

and constructed by engineers have been damaged during earthquakes

because of disregarding the negative effects of walls. Apart from the poor

quality of construction and materials, inattention in design process is the

main reason for undesirable seismic behaviour of walls.The main aim of

this paper is to investigate the measures taken in different stages of

architectural and structural design for improving the seismic behaviour of

infilled concrete structures. As a general principle, with the further

progress of project from basic architectural design to detailed structural

design, there is a need to reduce designer authority and increase obligation,

furthermore the cost of project increases too. The conclusion of this study

implies that, in order to achieve the desirable seismic behaviour of walls,

close collaboration between architects and structural engineers is required

from the early stages of design. The results of this study are presented in a

check list for designing reinforced concrete (RC) moment resisting frame

and RC shear wall.

Key words: Walls, Seismic Behaviour, Architectural Design, Structural

Design, Concrete Structures
