Seismic Performance Assessment of a Moment-Resisting Frame Steel Warehouse Provided with Overhead Crane

Abstract

The purpose of this study is to analyze the nonlinear behavior of a steel warehouse structured by moment-resistant frames, which utilizes an overhead crane on its interior brackets and as an external load of the weight of the lining panels. The analysis methods used are (i) pushover analysis, which consists of applying an incremental force in the transverse and longitudinal direction to obtain the capacity curve of the structure; (ii) time-history analysis, in which different records of destructive earthquakes that occurred in Chile are used in order to analyze the response of the structure to these loads. The results indicate that the transverse direction is more ductile than the Y direction of the structure within the pushover and time-history methods but not using the N2 method. It is also found that most of the columns are within the life safety and collapse prevention criteria. It is concluded that most of the analyses agree with each other and with what is expected, except for the N2 method, which contradicts the results of the time-history analysis, so the N2 method would not be suitable for this type of structure. In addition, it has been determined that the overhead crane loads do not substantially affect the seismic performance of the warehouse.

Artificial Neural Networks for seismic demand prediction of a single degree of freedom

“…However, both methods are time-consuming and require expertise to perform correctly. For that reason, several methods have been proposed to determine the seismic demand or the performance point of buildings when subjected to earthquake excitation [5] [6], [7] [8] FEMA 356 [9] introduced two methods to calculate the performance or target points. The capacity spectrum method (CSM) [10] is based on transforming the obtained pushover curve that represents the base shear versus the roof displacement into another acceleration displacement response spectrum (ADRS) representation.…”

Application of Fuzzy PID Based on Stray Lion Swarm Optimization Algorithm in Overhead Crane System Control

“…Therefore, the construction industry needs to design a stable and efficient anti-interference controller for the bridge crane system and realize automatic control of the bridge crane system. There are many studies in this field [11][12][13][14].…”
