In the field of structural health monitoring (SHM), vibration-based damage detection is an important technology to ensure safety civil structures. By taking advantage deep learning, this study introduces a data-driven method that combines convolutional neural networks (DCNN) and fast Fourier transform (FFT). method, vibration data are fed into FFT acquire frequency information reflecting condit...

In determining the seismic performance of reinforced concrete (RC) structures in national and international earthquake regulations, it is desired to use effective section stiffness cracked RC structural elements during design phase. Although not constant, depends on parameters such as strength reinforcement ratio. this study, beam models with different strength, tensile compression ratios were ...

This work proposes a methodology to optimize reinforced concrete structure. For this, the Whale Optimization Algorithm (WOA) algorithm was used, an from group of metaheuristic algorithms, which presents easy computational implementation. As study object, frame structure adapted real building subjected dynamic action artificially generated synoptic wind. The objective function is reduce volume t...

Abstract This paper presents a study that determines the conditions of testing for determining bounding properties seismic isolators use in analysis and design test is meant to be replacement tests Items 2(a) 3 ASCE/SEI‐7. Then separately, adequacy maximum considered earthquake Item 4 The are determined by performing analyses with models account time‐variant computing resultant isolator displac...

Traditional design of ship structures relies on a combination of experience, sound judgment, and deterministic approaches and typically ignores the potential for design improvement and other benefits offered through the use of reliability methods and structural optimization strategies. Part I of this article outlines the underlying theories involved in incorporating reliability methods and stru...

Doğrusal olmayan statik prosedür (NSP) veya itme analizi basitliği nedeniyle, yapısal ve elemanların performanslarının hesaplanması için kullanılmaktadır. Modelleme yapılırken yapıdaki her bir elemanın doğrusal özelliklerinin deformasyon kapasitelerinin belirlenmesi gerekmektedir. İtme analizi, TBDY 2018 ASCE 41-17 yönetmeliklerine göre, kullanıcı tanımlı plastik mafsal özellikleri varsayılan g...

In this study, the target evaluation building is a reinforced concrete structure with 4 stories in Surabaya City Indonesia that was over 35 years old. The method used U.S standard; ASCE 41:17 and Japanese JBDPA. results using 41-17 Tier 1 checklist 975 earthquake return period (BSE-2E) collapse prevention performance obtained several items received noncompliant (NC) status. Out of 21 items, 5 w...

The present study offers a deductive design procedure based on designs that have been optimally screened in accordance with ASCE 41-17's nonlinear static (NSP). subsequent phase inferred linear methodology from the philosophy underlying NSP of 41-17. deduced is applied to provide set optimal 6-story SMRF under two load patterns: code-based and first-mode shape patterns. by proposed are compared...

This paper presents a numerical study on structural behaviour of cold-formed stainless steel channels with circular web holes, under interior-one-flange loading case. The material properties types EN 1.4509 (Ferritic), 1.4462 (Duplex) and 1.4301 (Austenitic) were taken from the literature. In order to influence hole size, location load-bearing length crippling strength such sections, parametric...
