The purpose of the study was to investigate the behavior fully-saturated soft clays subjected to self-weight loading from an old masonry structure of Abu Serga church which is the oldest church in Egypt dating back to the fifth century A.D and located in old Cairo area in Cairo city. 3.6 Typical load-deflection curve for fiber reinforced concrete in flexure.This research presents the damage mechanism of a historical masonry architecture induced by differential settlement based on 3D FE analysis. Approaches for (simplified) performance-based seismic analysis of a typical anchored sheet pile quay wall are proposed as a result of the research.6.5 Three Dimensional Analysis Verification of Plaxis 2D Wall Friction. PLAXIS 2D calculation results are used to validate simplified and simplified dynamic analysis results and to gain insight in the seismic failure behaviour of the anchored sheet pile quay wall.Plastic modeling or Mohr–Coulomb model in advanced soil was used during the various stages of numerical analysis. The present research presents an attempt and pilot study to design the PLAXIS 3D FE model to simulate ground problems, and to distort and analyze the stress of the complex structure of the Abu Serga church, which is loaded on plane level. Numerical analysis for such geotechnical problems is largely expected to contribute to the conservation of cultural heritages. The land area is also susceptible to floods. The main objective of the present study is too accurately record and analysis the geotechnical problems and induced structural failure mechanisms observed and calculated in the field, experimental and numerical studies.
Given the lifespan of such structures, several dynamic geological processes (weathering/erosion, surface movements and earthquakes) usually have a dramatic impact on the integrity of the monuments.PLAXIS 2D the problem is modelled using the Axisymmetry model and the 15-Node element. Hyperbolic stress-strain relation in primary loading for a standard drained tri-axial.Historical monuments are invariably exposed to the influence of the geological environment. Finally, the study represents the design studies and implementation of the inter-organizational retrofitting intervention and strengthening project for the oldest Coptic church in Egypt.Dynamic Load Plaxis arpn journal of engineering and applied sciences jeas, the design of a piled through mass gravity stone strong, the effect of tunnel lining modelling approaches on the, rs2 2d finite element analysis with shear strength reduction, facilities civil environmental and architectural, slope stabilityEngineering companies and institutions rely on PLAXIS 2D for every. ![]() The Mohr–Coulomb model is used for both static assembly and rigidity inspection. It is a program produced for the geotechnical construction plan and inquired about it and was used late as part of the structural and geotechnical survey. PLAXIS 3D (PLAXIS v.b 2018) was used to calculate the soil settlement due to consolidation and the impact of its accompanied pressures and stresses on the superstructure. Geotechnical numerical modeling of complex soil structure problems requires advanced three-dimensional advanced soil models. To determine the magnitude of stresses, analyze the deformation and settlement of the soft silty clay soil and the superstructure response, an analytical coupled model of geotechnical and structural engineering is presented in detail. Bach sheet music free musicThe averaged results indicated that (1) Physical properties, for specific gravity (Gs) it is ranged between 1.8 and 2.0 g/cm 3, water absorption (Wa) is 20.1%, Porosity (n) is 27%. And Provest , secondary loading surface model built by Hashiguchi in 1993, the plasticity model of sand based on multi-mechanism conception under cyclic loading by Kabilamany, Pastor et al.The evaluation methodology which has been followed for the structural rehabilitation of Abu Serga church (which is located in old Cairo area in Cairo) comprised the following phases/actions, as summarized in Table 1.Thirty brick samples and specimens have been collected from different locations in the structure of Abu Serga church, and the physical and mechanical testing have been achieved in the Laboratory of Building Materials in Faculty of Engineering in Cairo University by the author. The dynamic model based on other types of plasticity theory, such as multi-surface model built by Mroz et al. Building model under monotonic loading and using relatively complicated hardening law, such as the model based on modifier Cambridge model by Carter , the Desai model with single yield surface built in 1984. Since 1970s, there are extensive studies on elastic–plastic model about saturation soil under dynamic loading. Constitutive models are the key-stone not only for understanding the mechanical behavior of soils but also for carrying out numerical predictions by means of the FE method. Forex factorySpecific density, water absorption, porosity, ultrasonic velocity uniaxial compressive strength σ c, static modulus of elasticity, dynamic modulus of elasticity, and shear stress).Ten marble samples and specimens have been collected from the fallen fragments and from different deteriorated locations in the marble columns inside Abu Serga church. They have wide range values of their physical and engineering characteristics (e.g. They are of medium density, high porosity due to the weathering activities (subsurface water and salt weathering. The bricks have various colors and dimensions and formed mainly from local raw material (Nile sediments) together with some additives (rice hush and/or plant ash to improve their properties. Generally the studied fired brick is formed mainly of quartz and feldspar grains.These grains are embedded in a ferruginous dark brownish groundmass formed mainly of iron oxides (hematite) and burnt clays. The results from the physical and mechanical testing referred that the main construction materials of the church which is the bricks are in advanced state of deterioration and demand a necessary strengthening and retrofitting interventions.Red bricks and the hydraulic mortars were of the most important construction materials used in the Coptic churches including the subject of the present study “Abu Serga church” in the old Cairo. (2) Mechanical properties, uniaxial compressive strength (σ c) is 8 MPa, Brazilian splitting tensile strength (σ t) is 3 MPa, Static Young’s modulus (E) is 7 GPa.Abu Serga church is a small chapel with a length of 29.4 m and a width of 17 m and a height of 15 m. The field observation and the averaged results of the mechanical testing indicated that the structural wooden beams which support the roof are deflected in high value due to the overloading and the material decay and degradation (1) physical properties, for specific gravity (Gs) it is ranged between 0.64 to 0.69 g/cm 3, Water absorption (Wa) is 30%. The results indicated a very poor mechanical characterization of these marble columns which could affect the stability of these structural columns and induced the deformation patterns which is obvious.Four wooden samples and specimens have been collected from different locations in the roof of Abu Serga church. (2) Mechanical properties, uniaxial compressive strength (σ c) is 16 MPa, Brazilian splitting tensile strength (σ t) is 6 MPa, primary wave velocity (Vp) is 2.87 km/s, static Young’s modulus (E) is 30 GPa, dynamic Young’s modulus (Edy) is 11 GPa, and Shear modulus (G) is 1195 MPa. Typical Dynamic Loading For Plaxis 2D Series Of ArchesModern architectural surveys and studies presented in this study indicated that the length of the church is 29.40 m and its total width, including the external open court accompanying 24.50 m, as shown in Figs. These two rows of columns are divided into three long shallow domes, which can be considered a plateau with northern and southern passages. The height of the Holly crypt is about 6.5 × 5 × 2.5 m with two columns rows containing a longitudinal series of arches on each row. In the northern and southern ones, there are internal underground stairs leading to the Holly crypt. It features a typical basilica design with a gallery leading to a nave with two side aisles, and these passages are separated by twelve equal marble columns of row.Three sanctuaries occupying the eastern side of the church.
