Thus, the stakeholders involved in construction projects in the World need to understand the interpretation of FIDIC provisions against a background of civil law. This literature study will explore the identification of risks that occur in international projects using FIDIC contracts. A systematic review and detailed content analysis of 30 articles selected from respected academics and relevant journals published over the past three decades was carried out. The findings of risk identification are divided into 5 namely (1) Planning and Design, (2) Construction, (3) Operations & Maintenance, (4) Political Environment and (5) Social Economic. This study trying to identify, investigate, and classify the strongest factors that are considered to influence delays in construction projects. From the results of grouping identification, it is found that the greatest risk in FIDIC construction contracts is when the construction work is caused due to the complexity of the problems at the time of the construction, whether the dispute, payment or claims of work results. Recommendations from the authors would be good for the relevant stakeholders the project uses the FIDIC contract to further study the contents of the contract to help reduce or at least minimize the risk of project delays, especially during construction.}, keywords = {Risk Identification,Fidic contract}, url = {https://www.arce.ir/article_106040.html}, eprint = {https://www.arce.ir/article_106040_3cad4fe3955f496537d2e2a013677dae.pdf} } @article { author = {Abdel Rahim, Khalid Abdel Naser}, title = {State of Art: The Fire Resistance of RC Members Strengthened with CFRP Laminates}, journal = {Advance Researches in Civil Engineering}, volume = {2}, number = {1}, pages = {13-48}, year = {2020}, publisher = {Papyrus Press}, issn = {2645-7229}, eissn = {2645-7229}, doi = {10.30469/arce.2020.106043}, abstract = {The available current research on mechanical behavior of RC structural members strengthened with CFRP material resulting from fire is presented and technically discussed in this paper. This includes design reviews, methods of application and techniques of reinforcing RC members with CFRP. Besides, the review includes the latest developed experimental, numerical, methods and formulation studies. Moreover, most of the studies agreed that there is a need to conduct more parametric numerical analysis in the field for improvement the global thermal response and flexural strength of the RC members strengthened with FRP. Based on the missing research, this review paper propose and suggest a set of very innovative design strategies and methods of application to improve the fire response of FRP laminates in case of fire, such as, (1) a combination design reinforcement technique on RC structural beam members with a combined mechanically anchored 3NSM extruded FRP design, (2) RC structural members external bonded with zigzag shaped FRP strips at the bottom and side soffits, (3) installing steel wire mesh, textile wire mesh and carbon tissues as a reinforcement material in the fire protection layer, (4) testing the fire response of using π-anchor and FRP anchor devices and new shaped memory alloy material in RC structural members strengthened with FRP, (5) u-shaped steel anchorage plate installed in the mid-span of the RC FRP beam, (6) suggesting installing L-shaped steel plate as a form of anchorage tool to support the bottom and the vertical soffits of the extruded FRP and (7) fire response of RC beams strengthened with FRP laminates using 3 different pre-fabricated types of extruded FRP laminates. The aim of this paper is to contribute for a more effective research on this field, leading to a future wide use of this technique in safer RC structures to fire events.}, keywords = {Fire resistance,RC,beams,CFRP,Laminates}, url = {https://www.arce.ir/article_106043.html}, eprint = {https://www.arce.ir/article_106043_ea35b73a852f6b60abc62c945ec1c4da.pdf} } @article { author = {Karimzadeh, Sadra and Matsuoka, Masashi}, title = {Ground Displacement and Building Damage Estimation of the 2017 Kermanshah Earthquake Using SAR Remote Sensing}, journal = {Advance Researches in Civil Engineering}, volume = {2}, number = {1}, pages = {49-56}, year = {2020}, publisher = {Papyrus Press}, issn = {2645-7229}, eissn = {2645-7229}, doi = {10.30469/arce.2020.106048}, abstract = {We used two synthetic aperture radar (SAR) datasets with different resolution to monitor the Kermanshah earthquake displacements and the buildings in Sarpole-Zahab town. We have obtained two high resolution dual-polarized (HH and HV) ALOS-2 images in strip map (SM) mode and three dual-polarized (VV and VH) Sentinel-1 images in interferometric wide (IW) mode from ascending orbits. The incidence angle of ALOS-2 and Sentinel-1 datasets were 36.2° and 38.9°, respectively. Temporal baseline of ALOS-2 dataset is 42 days, whereas pre-event and co-seismic temporal baselines of Sentinel-1 dataset are 13 and 18 days, respectively. Human activities after disasters increase and deteriorate the damage proxy maps which sometimes make the damage proxy maps meaningless. Thus, we need post-event images with shortest gaps with the event. Since the revisit cycle of ALOS-2 is rather large, we only use two ALOS-2 images to calculate ground displacement}, keywords = {SAR remote sensing,Kermanshah Earthquake,Damage detection}, url = {https://www.arce.ir/article_106048.html}, eprint = {https://www.arce.ir/article_106048_42b441c6125eb420f54a00f6947cc7a0.pdf} } @article { author = {Katal Mohseni, Peyman and Zahedi- Khameneh, Amin and Khodaverdlou, Zahra}, title = {The Influence of Geometric Characteristics on The Performance of Steel Shear Wall}, journal = {Advance Researches in Civil Engineering}, volume = {2}, number = {1}, pages = {57-68}, year = {2020}, publisher = {Papyrus Press}, issn = {2645-7229}, eissn = {2645-7229}, doi = {10.30469/arce.2020.106049}, abstract = {The aim of this study is to investigate the mutual effect of geometrical properties of steel shear walls on their performance. This study was numerically performed using ABAQUS finite element software for simulation. In this study the effect of the diameter of the openings to the steel shear wall height ratio and the hardeners angles have been studied nonlinearly. The results show that as a result of the opening of the sheet, the shear resistance decreases proportionally to the decrease in its cross-sectional plane, but on the other hand, it increases the steel plate shear wall ductility and the 8% diameter is the largest diameter of opening which has a good effect on shear wall performance and the presence of reinforcing elements such as hardener increases the hardness of the steel shear wall and in this case it shows that using cross hardeners has the most effect in absorbing the energy of steel shear wall.}, keywords = {SPSW,Energy absorption,Non-linear analysis,Opening and stiffener}, url = {https://www.arce.ir/article_106049.html}, eprint = {https://www.arce.ir/article_106049_661ddfa876282f9b994e30002df04bc4.pdf} } @article { author = {Assatourians, Armen and Mehrdoust, Mohammad Reza and Fallahi, Sohrab}, title = {The Effect of using Additional Isolated Upper Floor on the Performance Point of R.C.
