Bearing capacity of ring foundation due to various loading positions by finite element limit analysis This paper investigates the effects of the footing loading position and the footing radii ratio (ri/ro) on the normalized bearing capacity. Both smooth and rough footings located on frictional and cohesive soils are evaluated by finite element limit analysis (FELA). Quadruple tests (i.e., T1, T2, T3 and T4) are propounded to reach the main goal in this study. The obtained results are presented in the form of normalized bearing capacity charts and the failure patterns for each condition. Based on the analysis, a nonlinear model is proposed to estimate the bearing capacity of a ring footing subjected to varying loading positions. منبع @Civilbest_Bearing_capacity_of_ring.pdf

Design problems of anchoring of aboveground steel tanks Lyubomir A. Zdravkov1 Keywords: aboveground steel tank, anchor, anchor’s chair, radial deflection, stress Research area: steel structures SUMMARY Aboveground steel tanks are spatial sheet structures. The loads which impact on them are self-weight, snow, wind, earthquake, overpressure and vacuum. When the earthquake, overpressure and wind loads have high values, it is possible that the tank overturn or going to slide. To eliminate the threat from free moving, the steel facilities are often anchored to the foundation. This solution is not recommendable, and in standards [1] and [2] it is positioned on the last place. Despite the standard’s recommendations when the conditions of exploitation are strait and/or extreme, the steel vertical tanks must be anchored. Because of it, the developing of new specific details is needed on the purpose to minimize their unfavourable effects. منبع @Civilbest_طراحی_مهار_،_مخازن_رو.pdf

Failure analysis of RC shear walls with staggered openings under seismic loads تحلیل گسیختگی دیوارهای برشی بتن مسلح با بازشوهای شطرنجی در بارهای لرزه ای Marius Mosoarca a b s t r a c t Reinforced concrete shear walls are used to design buildings located in seismic areas, because of their rigidity, bearing capacity and high ductility. Until now many theoretical and experimental tests on shear walls with or without openings have been made, therefore their failure modes have been analysed and are rather very well-known; the research results being confirmed by real failure modes of RC walls after earthquakes. Design codes and standards based on the knowledge of the failure modes of the reinforced concrete walls were developed in order to obtain the ductile failure mechanisms. A special case is the failure mode of the reinforced concrete shear walls with vertical staggered openings. If at coupled walls the elements must be designed so that the plastic hinges appear at the ends of the coupled beams and then in the pier, this thing is more difficult at shear walls with staggered openings. Theoretical and experimental studies on structural walls with staggered openings, lamellar walls and walls with bulbs at the end have been made recently. There have also been studied the followings: the degradation of the stiffness, the ductility function to the intensity of the seismic force, the presence of the vertical forces, the position and the size of the openings and the reinforcing ways. The article presents the results of the theoretical and experimental tests on failure modes of three types of reinforced concrete shear walls with staggered openings which are compared to those obtained from walls with vertical ordered openings as far as the seismic response is concerned. The failure modes of the structural walls under seismic stress have been identified using calculus programs and cyclic alternated experimental tests. The theoretical research on the failure modes was the basis for the elaboration of a simplified methodology for the calculus of the maximum theoretical seismic force that produces the concrete crushing in the ultimate limit stage. The results theoretically obtained with the help of the calculus programs have been confirmed experimentally. The analysis of the failure modes, obtained with the computing methodology proposed, contributed to the completion of the seismic design codes for shear walls with staggered openings. منبع عملکرد_دیوارهای_برشی_بتنی_با_بازشوهای.pdf

Single Piles in Liquefiable Ground : Seismic Response and Numerical Analysis Methods Abstract The seismic response of piles in liquefiable ground is an important and challenging topic in the field of geotechnical earthquake engineering. Through a combination of case analysis, centrifuge shaking table experiments and numerical simulations, the seismic response patterns of single piles in liquefiable ground are revealed, and the axial pile force and settlement during post-earthquake reconsolidation is studied. A complete set of numerical method for the analysis of single piles in liquefiable soils is established, consisting of constitutive formulations, numerical algorithms and modelling techniques. The main achievements are as follows: 1. A three-dimensional unified plasticity model for large post-liquefaction shear deformation of sand is formulated and implemented for finite element analysis, based on which a three-dimensional dynamic finite element analysis method for piles in liquefiable ground is developed. The constitutive model is able to achieve a unified description of the behaviour of sand at different states under monotonic and cyclic loading during both pre- and post-liquefaction regimes. Appropriate stress integration algorithm, three-dimensional stress projection algorithm and parallel computation techniques are applied in the OpenSees implementation of the model. The potential of the model and its numerical implementation are explored via simulations of classical element and centrifuge experiments. The finite element analysis method is validated against centrifuge shaking table experiments. 2. Methods for the analysis of consolidation and reconsolidation-induced pile axial force and settlement with a consideration for consolidation process are proposed. A beam on nonlinear Winkler foundation (BNWF) solution and a modified neutral plane solution are developed and validated against centrifuge experiments for piles in consolidating and reconsolidating ground. 3. The seismic response of single piles in liquefiable ground is studied, including basic force-resistance mode, kinematic and inertial interaction coupling mechanism and major influence factors. The roles of kinematic and inertial effects could differ due to the difference in rotational constraint at the pile head. Moment caused by kinematic and inertial interaction is opposite for single piles with pile cap, while being of the same direction for single piles without pile cap. The total moment caused by dynamic interaction is affected by both the amplitude and the phasing of the two types of interactions. The dominating forces for piles with and without caps are kinematic and inertial forces, respectively. Pile residual moment increases with increasing lateral spreading in sloping ground. The existence of a non-liquefiable layer over the underlying liquefiable layer may cause the maximum moment to occur at the layer interface. 4. The axial forces and settlement of piles during post-earthquake reconsolidation were analysed. The maximum pile axial force caused by post-earthquake induced negative friction is irrelevant to the reconsolidation process, and is only determined by the final state of the ground. However, pile settlement is dependent on the soil settlement at the neutral plane during reconsolidation, while the neutral plane position changes during the reconsolidation process.

Numerical simulation of seismic collapse mechanisms of vertically irregular steel high-rise buildings Reza Ramezani Azghandi a, Hamzeh Shakib a,⁎, Maedeh Zakersalehi b a Tarbiat Modares University, Tehran, Iran b Niroo Research Institute, Tehran, Iran a b s t r a c t The effect ofmass and stiffness vertical irregularities on the collapse mechanismand resistance of steel high-rise structures is investigated using 3-D numerical simulations. Simulations are carried out utilizing a verified modelling approach in which the collapse processes of a regular and four irregular structures are studied under 11 earthquake records. It is indicated that the utilized finite element model, related considerations and calibrations present a reliable and efficient technique for collapse simulation. The findings showthat vertical irregularities adversely affect the collapse resistance and mechanism of steel high-rise buildings. Especially, mass vertical irregularity with concentration in the lower half of the structure is the most vulnerable one; while the stiffness irregularity with distribution in the top and bottom parts of the structure is the least affecting one. Studying the simultaneous effect of frequency content and vertical irregularities shows that, generally, records with wide frequency content mostly reduce the collapse resistance of the structure and have no significant effect on the collapsemechanismof irregular structures in comparisonwith regular structure;while records with medium frequency content are most effective on the collapse mechanism. منبع 10.1016@j.jcsr.2019.105914.pdf

Effect of distribution pattern of DSM columns on the efficiency of liquefaction mitigation Abstract. Liquefaction during earthquakes can result in severe damage to structures, primarily from excess pore water pressure generation and subsoil softening. Deep Soil Mixing (DSM) is a common method of soil improvement and is also used to decrease shear stress in liquefiable soils to control liquefaction. The current study evaluated the effect of Deep Soil Mixing (DSM) columns and implementation of different column patterns on controlling liquefaction and decreasing settlement of shallow foundations. A series of shaking table physical modelling tests were conducted for three different distribution patterns of Deep Soil Mixing (DSM) columns (i.e.: square, triangular and single) with a treatment area ratio of 30%. The treatment was applied to a liquefiable soil under a shallow model foundation. The results showed that the excess pore water pressure decreased 20% to 50% in comparison with the unimproved soil, depending on the Deep Soil Mixing (DSM) column pattern used. For improved soil, the shallow foundation settlement was about 10% that of the unimproved soil in the best case. The increase in soil shear stiffness after use of the Deep Soil Mixing (DSM) columns was compared with the results of existing practical relations to increase soil shear strength.
