“…The proposed SRM is applied to the Watwood [29] web-tapered gable frame in this section. The geometrical properties and loading conditions of the Watwood [29] frame, which is similar to an actual failed gable frame investigated by the author of [29], are illustrated in Fig. 11.…”

“…The frame has short stiff columns, which leads to the development of large axial loads in the rafters, which are inclined at a large angle to the horizontal, resulting in an instability sensitive frame. This feature of the Watwood frame [29] makes it an excellent benchmark example to be used in the validation of the proposed SRM. The frame was fabricated from steel with a yield stress of 344 MPa used for both flange and web plates, had a bay width equal to 6.1 m and had Z-section roof purlins spaced at 1.61 m, as [29] frame (all dimensions are in mm) illustrated in Fig.…”

“…A beam finite element model of the Watwood [29] frame was created through the MAS-TAN2 [30] structural analysis software considering the centreline dimensions and with the tapered members divided into prismatic segments using the actual cross-section properties at the middle of each segment, as shown in Fig. 12.…”

“…The same cross-section properties for each segment (i.e. element), loading values and nodal geometry used in the beam element model of Watwood [29] were adopted for the beam element model developed in this study. Detailed information with respect to all these properties of the beam element model is provided in Watwood [29].…”

“…The members of these frames are categorized as prismatic or non-prismatic sections. In non-prismatic in consecutive bays type, the cross-section is continuously varying from start to end of linear elements, and in prismatic type, the member has the same geometrical characteristics along the linear element [3,4].…”

The weight and shape of the gable and multi-span frames (mono and two-span pitched roof) with tapered members, as a familiar group of the pitched roof frames, are highly dependent on the properties of the member cross-section. In this work a quantum inspired evolutionary algorithms, so-called Quantum evolutionary algorithm (QEA) [1], are utilized for optimal design of one gable frame and a multi-span frame in five alternatives with tapered members. In order to optimize the frames, the design is performed using the AISC speciﬁcations for stress, displacement and stability constraints. The design constraints and weight of the gable and multi-span frames are computed from the cross-section of members. These optimum weights are obtained using aforementioned optimization algorithm considering the cross-section of members and design constraints as optimization variables and constraints, respectively. A comparative study of the QEA and some recently developed methods from literature is also performed to illustrate the performance of the utilized optimization algorithm and its featuring. Furthermore, optimal design of a multi-span frame is compared with the solution of other methods including the same conditions and constraints. This study indicates the power of QEA in exploring and exploitation due the search space with using Q-gate and binary code for individual representation and updating. Binary code helps the QEA to find optimal solution even with minimum number of Q-bit individuals. High speed of this method is because of such a feature.
