“Computational Civil Engineering - "Intersections" International Journal

“Computational Civil Engineering 2005”, International Symposium 9Paulet-Crainiceanu, in [24], is developing the means for active hinges to be used incontrolled structures. This study is a step forward for the analysis of such controlledstructures, and also in the vision of robotic structures.Optimization of reinforced concrete bridge design is in the views of Ionescu, in [25].Optimization technique is described, in order to use some commercial finite elementcomputer programs. The concept of optimal design of bridges is also presented. Theiterative nature of designing process is underlined, but adequate methods could lead to limitthe number of needed iterations.A new type of joint assemblage for the thin-walled steel profiles is presented by Budescu,Ciongradi and Rosca, [26]. The KONTI type of element joints is taken into account.Because some common connections with HSFG bolt had proven lessening of bearingcapacity during tests, a new type of joints is proposed. The philosophy of the new type ofjoint is presented and tests were carried out. Good behavior of the new joints compared tocommon type was observed.Barsan and Ignat, in [27] and [28], are dealing with the optimization of boostersdisinfection in water distribution systems and with the impact of failures in that can occurin this water distribution systems. Models an analytical work is completed experimentalwork. These papers show a tremendous interest on behalf of the social community usingadvanced computational techniques.In [29], Tepes Onea is showing an analysis that takes into consideration the soil-structureinteraction in obtaining the non-linear dynamic response. An application is showing theway to make such computation for a hotel structure. Comparisons are performed with thecase of a common linear spectral analysis. Differences are underlined and commented.3. CONCLUSIONSComputational Civil Engineering is showing to be an important support layer of most CivilEngineering domain. Examples shown in this paper are covering large sub-domains fromCivil Engineering and the interaction that arises between them and Computer Sciencedomain. Studies and researches in Civil Engineering are developing and improving in partbecause of the use of computers and computation.References1.
