“…Bridge management and some pavement management take similar approach as well. This paper models this deterioration process as a continuous‐time Markov chain, which has been employed in the literature for different asset classes, for example, sewers (Ana & Bauwens, ; Baik et al., ; Le Gat, ; Wirahadikusumah et al., ), storm water pipes (Micevski, Kuczera, & Coombes, ), nuclear plant feeder pipes (Datla, Dinnie, Usmani, & Yuan, ), concretes (Bastidas‐Arteaga, & Schoefs, ; Sheils, O'Connor, Breysse, Schoefs, & Yotte, ), and bridges (Cesare, Santamarina, Turkstra, & Vanmarcke, ; Manafpour, Guler, Radlińska, Rajabipour, & Warn, ).…”

Deterioration modeling is an important analytical component in infrastructure asset management. It concerns the prediction of performance and remaining service life of assets of different designs under omnifarious working environments. For long‐term prediction, it also requires to characterize maintenance effectiveness because maintenance activities do not necessarily bring an asset to a completely renewed status. Deterioration modeling research has for decades been largely focusing on the modeling of the natural deterioration process per se, whereas the modeling of maintenance effectiveness is only a recent focus of investigation, mainly in pavement research. In practice, the asset conditions immediately before and after a given maintenance treatment both are not often known. This has made the modeling of maintenance effectiveness and long‐term deterioration prediction a challenging task. To bridge the gap, this paper presents a novel approach that integrates the modeling of deterioration and maintenance effectiveness into one process. The natural deterioration of asset performance is modeled as a continuous‐time Markov chain, whereas the effectiveness of a maintenance measure is modeled as a discrete‐time Markov chain. To account for missing condition data before and after the maintenance event, the paper also develops a robust statistical method based on Markov chain Monte Carlo simulation. A real‐life case study on a municipal sewer pipe system is carried out for demonstration of the proposed integrated modeling approach. The functional deterioration of sewer pipes and the effectiveness of flushing operations that target to bring flow capacity to intact state are modeled. Influences of pipe length, diameter, slope, and sewershed area are examined. The present work is a valuable step toward development of evidence‐based risk‐informed asset management framework.

“…The forces acting on the pile mainly include the landslide thrust or the soil lateral pressure, the cable tension, the reactive force of surrounding soil in the embedded section of the pile. The pile weight, the force acting on the pile bottom, the friction between the pile and the soil, and the vertical component of the earth pressures behind the wall are ignored [15,16].…”

Original scientific paper From investigations of damaged earth structures after earthquakes, anchored sheet pile wall has proved to be an excellent seismic structure. However, due to the complexity of the stress system, some fundamental theoretical issues have not been completely solved, so the theoretical development of the structure lags behind application, especially in the development of seismic design theory. In order to make up for this deficiency, a new simplified approach was proposed in this paper, based on previous research. In this approach, the dynamic coupling effect of the pile-soil-anchor was considered, and governing equations were established. In addition, to verify the applicability of the proposed approach, large-scale shaking table tests were performed. In the tests, similitude ratios and similar materials were appropriately applied, and horizontal and vertical acceleration time histories recorded at the Wolong station in the Wenchuan earthquake, China, were used to excite the model. Many time history curves, including dynamic and total earth pressures acting on the stabilizing pile, the cable tensions and the displacements of the wall were obtained. By comparison of the earth pressures and cable tensions between the calculations and tests, the correlation coefficient is 0,943 and 0,890 for earth pressures and cable tensions, respectively. It illustrates that the correlation coefficient between tested values and theoretical results using the proposed theoretical calculation approach is high and close to 1,0, and it is proved that the proposed approach is suitable for practical application. Keywords Novi pristup seizmičkom projektiranju ukotvljenog pribojaIzvorni znanstveni članak Istraživanja oštećenih zemljanih konstrukcija nakon zemljotresa pokazala su da je ukotvljeni priboj (zagat) odlična seizmička konstrukcija. Međutim, zbog složenosti sustava naprezanja, neka temeljna teorijska pitanja još nisu potpuno riješena te teorijski razvoj konstrukcije zaostaje za primjenom, posebice u razvoju teorije seizmičkog proračuna. Kako bi se nadoknadio ovaj nedostatak, u radu se predlaže novi pojednostavljeni pristup, temeljen na prethodnom istraživanju. U tom se pristupu razmatrao učinak dinamičke sprege stup (pilon, šip) -zemlja -anker (zatezač), a postavljene su i odgovarajuće jednadžbe. Uz to, kako bi se provjerila primjenjivost predloženog pristupa, provedena su opsežna ispitivanja trešenjem (shaking table tests). U tim su ispitivanjima odgovarajuće primijenjeni omjeri sličnosti i slični materijali, a podaci o vremenu horizontalnog i vertikalnog ubrzanja zabilježeni na Wolong stanici tijekom Wenchuan zemljotresa u Kini, primijenjeni su za pobuđivanje modela. Dobiveni su mnogi podaci, uključujući dinamičke i ukupne pritiske zemlje koji djeluju na stabilizacijski stup, zategnutost užadi i pomake priboja. Usporedbom pritisaka zemljane mase i zategnutosti užadi dobivenih proračunom i ispitivanjima, dobio se koeficijent korelacije od 0,943 i 0,890 za pritisak zemlje, odnosno zategnutosti užadi.

Abstract:This work focuses on assessing costs and effectiveness of climate adaptation strategies for existing reinforced concrete structures subject to chloride penetration and climate change. We will study on existing reinforced concrete structures built in France at different years under different building codes. Concerning environmental actions, we considered historical meteorological data and two climate change scenarios. It is hoped that the results of this study provide practical guidance to decision makers to improve the management of reinforced concrete structures under a changing climate.
