“…The aforementioned scholars have studied and discussed the application of the method to members, and in terms of different types of structural systems, Yang and Lu 27 proposed a direct displacement design method based on the concept of inelastic design spectrum for prestressed concrete shear walls and verified the applicability of the method by design examples. Boulaouad and Amour 28 used the displacement‐based design method to simulate single‐ and multi‐story buildings numerically, gave the basic principles and design steps of the method, and compared it with the force‐based method. The analysis results showed that the displacement‐based method is simple, efficient, and has sufficient accuracy.…”

Recycled aggregate concrete-filled square steel tube (S-RACFST) frame has the characteristics of high bearing capacity, good ductility, and superior seismic performance. To propose a displacement-based seismic design of S-RACFST frame, the validity of the design method was verified by a detailed calculation example. Based on the performance requirements, this design method divided the structural performance into five levels: normal use, temporary use, use after strengthening, life safety, and collapse prevention, and suggested specific steps for the displacement-based seismic design of S-RACFST frame using the inter-story displacement angle limit value as the quantitative indicator. The 10-story S-RACFST frame was used as an analytical example for static elasticplastic analysis. The pushover lateral displacement curves of the frame structure at each performance level were obtained and compared with the displacement-based seismic design curves. The results show that the displacement-based seismic design method of S-RACFST frame structures can fulfill the performance level requirements such as "temporary use," "normal use," and "collapse prevention," and the displacement-based seismic design method is one of the effective ways to realize the performance design of S-RACFST frame structures.

“…Because of its complexity, this procedure is used only for special cases. For current use, in order to meet the requirements for the several limit states provided by the different codes, a number of simpler design procedures were recently developed and jointly termed "Performance Based Seismic Design" (Boulaouad and Amour, 2010).…”

In some regions of the world subjected to frequent severe earthquakes, such as Algeria, attention is focused on seismic design in order to assure the public welfare. When, for many countries most of the building consists of constructions of "self-steady frames" type system. The last seismic events have shown the inefficiency of such a type of to avoid evident disaster. On the other hand, the use of shear walls as "Lateral Load Resisting System" (LLRS) seems to be a good alternative. This study tries to confirm the requirement of shear walls in seismic zones by highlighting their beneficial effect on structures subjected to strong motions. For this purpose, a comparison is made between the two types using both linear and nonlinear analysis with a focus on two parameters which are of great im-portance, the base shear and the lateral drift in particular. Applications are made on two types of Reinforced Concrete (RC) multistory structures: with shear walls (dual systems) and without (w/o) shear walls (self-steady structures). The results permit to emphasize the need of shear walls as LLRS in seismic zones and confirm the restrictions imposed by the Algerian code, amongst others, concern-ing the use of self-steady frames system for structures in such area.

Seismic design of Reinforced Concrete (RC) dual systems is performed as an optimization problem for which the charged system search algorithm is utilized as an optimizer. An efficient structural modeling is also presented for this purpose. Here, first databases are created based on ACI seismic criteria for beams, columns and shear walls. Formulations for optimal seismic design of dual systems (shear wall-frame) are proposed. With some modifications on these formulations, optimal seismic design of RC moment frames can also be performed. This procedure is along with ordinary design constraints and effective seismic design constraints. These constraints consist of beams, columns, shear wall design criteria, and some other seismic provisions. Cost of the structure is considered as the objective function. According to the results of the numerical example, the proposed methodology can be considered as a suitable practical approach for optimal seismic design of reinforced concrete shear wall-frame structures.
