There are significant differences between expectations and fulfillment in the building delivery process. Many researchers have emphasized the need for design strategies that establish a direct correlation between design proposals and building performance. One of the main objectives is to support performance-driven primary design, which occurs before the design performance modeling (DPM) phase. To achieve this, a case study of retrofitting existing buildings on campus is presented. A normative calculation approach is used to identify the optimal combinations of a dozen retrofit strategies based on the Energy Performance Calculator (EPC) model. This approach reduces or eliminates the impact of parametric uncertainties on modeling assumptions and simplifies calculations, particularly in restrictive studies. These retrofit solutions involve structural and functional zoning renovation, meaning that disparity between expectations and fulfilments is considered, and a timely related information feedback route to architects is achieved. In the first step of the narrative development of the EPC model, EPC-Calib was used to find the optimal combination of input variables in the model that satisfies the desired target and complies with the problem constraints. Secondly, the retrofit study was implemented with EPC-TechOpt, and 16 retrofit solutions for three design performance models were examined based on the local climatic conditions, building features, and retrofit costs. Finally, design schemes were determined, and the cost-optimal mix of the measures was desired with a 40% energy saving.

“…Traditional disaster prevention and resilience planning is accustomed to using engineering technical standard formulas or empirical values to calculate the safety requirements and to ensure the safe operation during a period. With the development of resilient civil infrastructure, an important premise and a critical guarantee to realize the city-scale resilience enhancement is the transformation to novel technology [8,9]. Compared with the conventional force-based civil infrastructure in design, the future resilient infrastructure will focus more on the performance theory and post-disaster function in the life-cycle procedure, and this largely depends on the improvement and upgrade of resilient technologies.…”

“…The initial objective is to determine if the loads imposed by the bridge crane are determinants in the results of the applied nonlinear analysis, and based on these results, the ASCE 41–17 [ 41 ] methodology will be applied to verify if the chosen sections for the structural members adequately respond to the loads imposed by a set of ground motions. The applied procedure could be used to introduce improvements in the design or to retrofit existing structures [ 42 , 43 ].…”

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

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.
