“…The standard value and design value of material strength were significant in the designing work of masonry structure. The probability distribution of material strength should conform to the normal distribution, and the standard value of material strength could be determined by the 0.05 quantile of probability (Jiang and Ye, 2020; Jiang et al, 2020; Liu et al, 2019c). Hence, the standard value fk could be calculated according to equation (2).…”

Comprehensively considering the positive contribution of energy conservation and the reduction of the construction skill requirement for workers, a new type of interlocking hollow block using recycled aggregates concrete (IHAC) with the compressive strength defined as MU10 was proposed, which could help improve more than 56% of the construction efficiency compared to common used concrete hollow blocks. In order to study the shear properties and promote its application in building engineering, the shear strength of 10 groups (three specimens for each group) of masonries considering different axial stress level and whether or not to use concrete in the grouting holes were studied, and the failure mode as well as the shear strength of the masonries were analyzed. And then, the calculation formulas for predicting the shear strength of the IHAC masonry were obtained by using the parameter fitting method based on the Coulomb failure theory, which could well reflect the parabolic shaped changing characteristic of the shear strength with the increasing of the axial stress, and the maximum difference was within 18% between the calculated and test results.

This study evaluated the influence of additional shear walls, constructed on the first floor, as strengthening methods for a piloti-type building subjected to earthquake loadings. Piloti-type buildings are commonly designed as urban structures in many cities of South Korea. The existence of just columns on the first floor of the building is a feature that is advantageous from an architectural viewpoint, and yet has potential structural disadvantages. Such columns usually exhibit shear–axial failure, due to inherent vertical and horizontal irregularities and insufficient seismic reinforcements. Among several retrofitting methods, including additional braces, carbon fiber reinforced polymers, dampers, and so forth, this research considered reinforced concrete shear walls to improve the seismic responses of piloti buildings. A parametric analysis of the location of the retrofitted shear walls in a typical piloti building was implemented using the Zeus-NL program. Nonlinear time history analysis and incremental dynamic analysis were performed to comparatively evaluate the structure’s seismic responses and fragility curves before and after retrofit.

“…[ 1 ] Therefore, in recent studies, the life‐cycle cost has been the seismic optimization goal of designing the control system for retrofitting (or seismic design) the structures. [ 2–9 ] Mitropoulou and Lagaros [ 3 ] investigated the performance and cost of seismic isolators using life‐cycle cost analysis. They showed that although the seismic isolator system is expensive, the life‐cycle cost is less than its fixed counterpart.…”

“…They demonstrated that utilizing more dampers can significantly reduce the expected life‐cycle damage costs of the supposed structures. Jiang et al [ 9 ] proposed a seismic life‐cycle cost assessment method for controlled steel structures. Life‐cycle cost assessment of the controlled structures expressed that the life‐cycle cost is the right choice for objective design in structural optimization.…”

This paper aims to achieve minimum life-cycle cost, by applying a seismic design optimization of the steel frames with semiactive magnetorheological (MR) dampers. The total life-cycle cost, which includes the initial constructional and expected damage costs, is an adequate goal to satisfy both employer and users. For optimal performance of the dampers, two fuzzy control systems are suggested, each having two different inputs. Results of numerical analysis for an 11-story steel structure show that using MR dampers decreases the interstory drift ratios to a permissible limit. It also reduces life-cycle cost when the design is optimum and when the dampers are evenly distributed by 23% and 14%, respectively. In the case where the objective function was to minimize the total life-cycle cost, the expected injury and fatality, as the most crucial financial parameters, had the highest decrease rate. There was also a 17% drop in comparison to the state that the dampers are evenly distributed. The fuzzy control with drift and velocity as inputs had better performance in minimizing the total life-cycle cost than the other fuzzy control, which used acceleration instead of velocity.
