This paper addresses the issue of historical urban centres from the perspective of the analysis and inventory of building features. The cataloguing process of the building typologies is presented herein as a synthesis of the main construction forms, using as a case study the old city centre of Seixal, Portugal, rebuilt in its present form after the great 1755 Lisbon earthquake. As marks of an historical and architectural heritage, old urban centres should be protected, safeguarded and potentialised. Therefore, it is essential to have a complete understanding of the diachronic process of both buildings and urban mesh, in order to support qualified, conscientious and sustainable interventions.

The process of bridges seismic retrofitting in the highway network is extremely costly and time consuming. In addition, the constraint on resources prevents the retrofitting of all the bridges at the same time. Besides, the bridges must be prioritized with simultaneous consideration of multiple criteria, including technical and socioeconomic aspect. This study intends to identify the major criteria and consider them simultaneously for prioritization of highway bridges additionally provides an effective technique for weighing these criteria. In this research, TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method as a Multi-Criteria Decision-Making (MCDM) model is applied. TOPSIS method enables decision makers to deal with problems involving a large number of alternatives (bridges) and criteria. This methodology reduces multiple alternative (bridge) performances into a single value (ranking score) to facilitate the decision-making process for determination of the most suitable bridges for retrofitting. Suggested criteria include structural vulnerability, seismic hazard, anticipated service life, average daily traffic, interface with other lifelines, alternative routes and bridge importance. Moreover, relative importance (weight) of the criteria is assigned using Analytic Hierarchy Process (AHP) technique. The proposed method is applied to a real case of the Isfahan highway network.

Seawater has a significant impact on hydrotechnical concrete structures in the Port of Klaipeda. This factor must be properly examined and evaluated designing reinforced concrete structures exploited in seawater. The basic aim of research is to assess the effects of seawater on concrete and to form an algorithm for studying the durability of hydrotechnical structures affected by seawater. The conducted investigation showed the impact of seawater on hydraulic engineering (concrete) structures. Serious defects are caused by corrosion in hydrotechnical concrete. The key factors indicating the durability index of hydrotechnical concrete include damage to the concrete due to environmental, mechanical and physical-chemical effects. Physical-chemical environmental effects occur due to changes in temperature, the speed of the wind and fluctuations in the sea-level. Multiple environmental impacts can simultaneously affect hydrotechnical concrete. Mechanical external effects occur due to constant stevedoring works and vessels moored at the Port of Klaipeda. Santrauka Klaipėdos uosto hidrotechniniams statiniams jūros vanduo daro didelį poveikį. Šis veiksnys turi būti ištirtas ir vertinamas projektuojant gelžbetonines konstrukcijas, eksploatuojamas jūros vandenyje. Darbo tikslas –įvertinti jūros vandens poveikį betonui bei sudaryti paveiktų jūros vandens hidrotechninių konstrukcijų ilgaamžiškumo tyrimų algoritmą. Tyrimų metu atlikta jūros vandens poveikio hidrotechniniams (betono) statiniams analizė. Klaipėdos uosto krantines veikia agresyvioji aplinka. Didelius defektus sukelia hidrotechninio betono korozijos. Hidrotechninio betono pažeidimai nuo aplinkos ir mechaninių, fizikinių ir cheminių poveikių yra pagrindinis veiksnys, darantis įtaką hidrotechninio betono ilgaamžiškumo rodikliui. Fizikiniai ir cheminiai aplinkos poveikiai atsiranda dėl temperatūrų kaitos, vėjo greičio, jūros vandens lygio svyravimų. Hidrotechninį betoną vienu metu gali veikti keli aplinkos poveikiai. Mechaniniai išoriniai poveikiai atsiranda dėl nuolat Klaipėdos uoste vykstančių krovos darbų, prišvartuotų laivų.
