  • Quasi-static Tests on 1:3 Scaled Arch Segments of the of the Old Bridge in Mostar   Order a copy of this article
    by Mladen Kustura, Goran Šunji?, Dragan ?ubela 
    Abstract: Abstract: Masonry stone arch, and other types of masonry structures, owed their durability through the centuries primarily to the inventiveness of the builders, who, by introducing new connection elements, managed to build structures that would resist various effects through the time. Connection elements used for assembling bridge vaults, or clamps and dowels made of wrought iron with the additional use of liquid lead and mortar, are one of the successful ways to increase stability and load-bearing capacity of this type of structures. A similar assembly technique was applied during construction of the original Old Bridge in Mostar in 1566 and its reconstruction in 2004. This paper presents experimental tests performed on 1:3 scaled arch segments of the Old Bridge in Mostar and obtained results. This experimental research was conducted in order to describe the behavior of all connection elements participating in the transfer of loads that can occur. Obtained results of the performed experimental tests are highly utilizable for further numerical analyses and verification of the existing and new mathematical models.
    Keywords: masonry arch; connection elements; quasi-static laboratory tests; failure mechanism; loosening of connection.

  • Verifying the Periods of Vibration for Different Structural Systems using Earthquake Data and Simulation   Order a copy of this article
    by Aman Mwafy, Aya AbouElhamd, Suliman Gargoum 
    Abstract: Although expressions for evaluating the fundamental period were recommended by building codes and previous studies, further research is still needed to evaluate the design formulas based on updated data collected from both instrumented structures and dynamic response simulation of realistic buildings. In this study, large fundamental period data from two sources are collected and compared with different expressions from building codes and previous studies. The first data set is collected from 147 instrumented buildings with various lateral force resisting systems (LFRSs). The second set is obtained from the inelastic dynamic response simulation of 26 multi-story structures. Seven LFRSs are considered, including steel moment-resisting frames (SMRFs), reinforced concrete moment-resisting frames (RCMRFs), concentrically braced frames (CBFs), eccentrically braced frames (EBFs), reinforced concrete shear walls (RCSWs), masonry buildings and pre-cast structures. The correlations between the collected period data with the code approach for predicting the fundamental periods confirm that the design provisions are conservative enough for different heights of SMRFs, RCMRFs, and CBFs in addition to EBFs higher than 40m. For low-to-medium rise RCSWs and EBFs along with low-rise masonry and pre-cast structures, recently proposed expressions in previous studies provide better conservative estimates for the fundamental periods. More data is highly needed to arrive at a reliable formula for the design of high-rise SW structures in different seismic regions. The study provides insights into the effectiveness of the current expressions for estimating the dynamic characteristics of buildings with different LFRSs and assist in arriving at a reliable and cost-effective design in earthquake-prone regions.

  • A New Row-Wise Parallel Finite Element Analysis Algorithm with Dynamic Load Balancing   Order a copy of this article
    by Ammar Al-Sayegh, Elisa Sotelino 
    Abstract: A parallel scheme is devised to efficiently parallelize all steps of Parallel Finite Element Analysis in this study. In addition, this scheme is based on a row-wise matrix distribution. A new Row-Wise Parallel Finite Element Analysis algorithm that exploits the nature of distributed compressed row sparse matrices and multivectors to improve concurrency is developed. A new dynamic load balancing technique has also been devised. The dynamic load balancing technique has been designed specifically to balance the computational workload among processors suitable for the analysis of nonlinear structures. This new algorithm has been implemented in ParaStruc, which is a parallel structural analysis system. Trilinos, a set of parallel numerical libraries developed by researchers in the Sandia National Laboratory has been used to build this algorithm. ParaStruc is a lightweight fully parallelized Parallel Finite Element Analysis system, which contains only three classes and a preprocessor. It is shown that this approach produces superior performance in terms of speedup, efficiency, and isoefficiency in the analysis of nonlinear structure response ranges when compared to parallel ABAQUS. The performance and efficiency of this algorithm has been verified with numerical simulations of a 200-meter 50-story 10-frame 10-bay 3-D structure subjected to various load levels.

  • Integrated cost-analysis approach for seismic and thermal improvement of masonry building fa   Order a copy of this article
    by Linda Giresini, Simona Paone, Mauro Sassu 
    Abstract: The combination of structural and thermal efficiency is a new frontier in civil engineering. Indeed, the retrofitting strategies should optimize costs and technical solutions from these two points of view. If a technical solution is able to provide an improvement of both structural and energetic behavior, then the utility of the intervention can better justify the economic investment. In this paper a mesoscale approach for integrated interventions applied on masonry fa
