The glass fiber reinforced plastics (GFRP) composite material is a low carbon emission, low life cycle cost, and sustainable material. In this paper, the structural behavior of the lateral force resistant performance of GFRP composite material frames with steel joints was presented, and the energy dissipation and failure modes of the GFRP frames were discussed. A total of six GFRP frames, including single-span and double-span frames with and without diagonal bracing members, were tested by pushover tests to obtain the lateral load-displacement relationships of the GFRP frames. The force-displacement relationship and the energy dissipation of the GFRP frames were examined in the pushover test. In addition, the numerical analysis was performed to obtain the lateral load-displacement relationships of the GFRP frames under pushover tests. When the numerical analysis results and the experimental results were compared, the absolute average errors of the maximum loads were less than 4%, and the lateral load-displacement relationships were close to each other. The numerical analysis results can predict the experimental force-displacement relationships of the GFRP frames.

Based on the present tecnology of pile, a method of compacted forming concrete pile applied in the subsea base is studied. Using the method of finite different the procedure of compacted forming at the end of steel pipe pile has been simulated in the particular geology soil, the effects of the elastic modulus, cohesion, friction and dilation on the compacted behaviour are aquired and the bearing capacity has been calculated. The results show that the ultimate bearing capacity of this pile increases approximate 3 times bigger than the steel pipe pile with the same dimentions, in addition, its curve of Q-S is smooth and ultimate feature point is indistinct, which proves that this tecnology of compacted forming concrete pile is able to increase the bearing capacity prominently.

Bridges are construction structures that are built to connect parts of the road that are cut off by obstacles such as deep valleys, irrigation channel paths. In order to build a bridge, a strong, economical and easy to build foundation is needed to carry gravity loads and also earthquake force. A common problem encountered in bridge foundation is the occurrence of erosion around the piles due to scouring of water which causes exposing some portion of the piles, which are often referred as elevated reinforced concrete pile-cap foundations. In this study, a numerical analysis of pile groups on elevated reinforced concrete pile-cap foundations is carried out with lateral forces on sandy soil to see the ductility behavior of piles using geotechnical-based programs and to compare the results with the previous studies. The analysis includes the pilecap model and the soil-to-pile interaction and also considers the pile group effect. The analysis was carried out to see the structural and geotechnical conditions on the ductility behavior of a partially embedded piles on sandy soil. The result obtained is a comparison of the ductility and overstrength values that can be used as a consideration in designing elevated reinforced concrete pile-cap foundations.Keywords: Elevated RC pile-cap foundations; numerical analysis; lateral force; ductility AbstrakJembatan adalah struktur konstruksi yang dibangun untuk menghubungkan bagian jalan yang terputus oleh rintangan-rintangan seperti lembah yang dalam, alur saluran irigasi. Untuk membangun sebuah jembatan, diperlukan fondasi yang kuat, ekonomis dan mudah untuk dibangun untuk memikul beban dari jembatan dan juga gaya gempa. Masalah yang umum ditemui pada konstruksi fondasi jembatan adalah terjadinya erosi pada sekitar fondasi dikarenakan gerusan air yang menyebabkan tanah terangkat dan memperlihatkan sebagian tiang fondasi, yang sering disebut dengan elevated reinforced concrete pile-cap foundations. Pada penelitian ini dilakukan analisis secara numerik terhadap kelompok tiang pada elevated reinforced concrete pile-cap foundations yang dibebani gaya lateral pada tanah berpasir untuk melihat perilaku daktilitas tiang dengan bantuan program berbasis geoteknik dan membandingkan dengan hasil penelitian terdahulu. Analisis menyertakan model kepala tiang dan hubungan antara tanah dengan tiang serta mempertimbangkan efek kelompok tiang. Analisis dilakukan untuk melihat kondisi struktural dan geoteknikal pada perilaku daktilitas fondasi yang ditanam sebagian pada tanah pasir. Hasil yang didapatkan adalah perbandingan nilai daktilitas dan overstrength yang dapat digunakan sebagai pertimbangan dalam mendesain elevated reinforced concrete pile-cap foundations.

Arch Bridges

This study was focused on the performance of the pile force at the lateral load of an arched bridge. The effect of the compression of arch bridges creates a large horizontal load. Therefore, it is one of the most important factors in the dimensioning of piles. The study aims to make a comparative study between the results obtained in the field, and those obtained by a 3D model defined as a Finite Element (FE) of a drilled pile, subjected to different lateral loads applied at exact time intervals. Moreover, the study was intended to determine the influence of the lateral load applied to a different pile diameter using the FE model. Thus, the unified FEA software Abaqus™ by Dassault systèmes® carried out various processing procedures, namely soil FE modeling, pile FE modeling, soil-pile interface, Mesh, and boundary conditions, to carry out an effective and predictive piles behavior analysis. Based on the Mohr-Coulomb criterion, the soil is considered to be stratified with elastoplastic behavior, whereas the Reinforcement Concrete Pile (RCP) was assumed to be linear isotropic elastic, integrating the concrete damage plasticity. Since the bridge is an arched bridge, the lateral load induced was applied to the head of the piles through a concentrated force to check the pile strength, for which the displacement, stress and strain were taken into account throughout, along the pile depth. The lateral displacement of the pile shows a deformation of the soil as a function of its depth, with different layers crossed with different lateral loads applied. Thus, from the study comparing the results of the FE measurements with the data measured in the field, added to the statistical analyses are as follows: Decrease of the displacement and stress according to the diameter, taking into account the different diameter. The foundations receive loads of the superstructure to be transmitted to the ground. Thus, the piles are generally used as a carrier transmitting loads on the ground. One of the important factors in the durability of the bridge depends more on the strength of these piles. This makes it necessary to study the reinforced concrete foundations because of their ability to resist loads of the structure, and the vertical and lateral loads applied to the structure. This implies an evaluation of the responses of the RCP according to the different lateral loads.

Composite piles use fiber-reinforced polymers (FRPs), plastics, and other materials to replace or protect steel or concrete, with the intent being to produce piles that have lower maintenance costs and longer service lives than those of conventional piles, especially in marine applications and other corrosive environments. Well-documented field loading tests of composite piles are scarce, and this lack of a reliable database may be one reason that composite piles are not in widespread use for load-bearing applications. The purpose of this research is to compare the axial and lateral load behavior of two different types of composite test piles and a conventional prestressed concrete test pile at a bridge construction site in Hampton, Virginia. One of the composite piles is an FRP shell filled with concrete and reinforced with steel bars. The other composite pile consists of a polyethylene plastic matrix surrounding a steel reinforcing cage. The axial structural stiffnesses of the prestressed concrete pile and the FRP pile are similar, and they are both much stiffer than the plastic pile. The flexurel stiffness of the prestressed concrete pile is greater than that of the FRP pile, which is greater than the flexural stiffness of the plastic pile. The axial geotechnical capacities of the test piles decreased in order from the prestressed concrete pile to the FRP pile to the plastic pile. The prestressed concrete pile and the FRP pile exhibited a similar response for lateral load versus deflection, and the plastic pile was much less stiff in lateral loading.
