The influence of soil foundtion consideration method on the dynamic characteristics of the building frame has been studied. The object of the study is a monolithic reinforced concrete frame. Modeling of the calculation model according to the scheme \"soil foundation - foundation - topside\" was performed .Three finite element models have been developed with a variation of taking into account the soil base. Absolutely rigid base, malleable Winkler base and dynamic Savinov foundation are considered. As a result of the dynamic calculation, the frequencies and periods of natural oscillations of the building frame were obtained. Comparison of the obtained results based on three versions of the models has been made. An optimal method for taking into account the soil foundation in the modeling of the soil foundation in the dynamic calculation of the frames of multi-story-buildings is proposed.

Due to rapid urbanization, open excavations are not uncommon these days. However, many issues are arising during the execution of unsupported open excavations when not designed and executed properly. Moreover, in urban areas where new buildings are constructed closer to the existing buildings, these excavations may affect the structural integrity of the adjacent existing buildings. Therefore, there is a need to evaluate the response of multistorey building frame (MBF) subjected to nearby series of unsupported open excavations. In the study, a numerical investigation on response of RCC-MBF structure with raft foundation resting on medium dense sand subjected to adjacent unsupported open excavations is performed using a 3D finite element program PLAXIS-3D. The series of open excavation is simulated considering the different geometrical parameters of excavation, such as varying setback distance, and different excavation volumes. As a response, the four parameters are monitored in the columns of the MBF i.e., displacement of the structure in x- and z -directions (i.e., settlement and tilt), and redistributed bending moments and shear forces in the column of MBF. The linear and non-linear analyses are performed to account the effect of constitutive models on the response of the MBF by assigning the Linear–Elastic and Mohr–Coulomb soil constitutive models to the soil respectively. Further, a sensitivity analysis is performed to evaluate the effect of strength and deformation parameters of the soil, and the geometrical parameters of the excavation on the factor of safety of excavation slope. Based on the results, it is observed that Mohr–Coulomb constitutive model can be used to analyse the response of structure subjected to unsupported open excavations. Finally, the effect of different foundation schemes is also analysed in the study.

The article presents a methodology for assessing the stability of construction objects to seismic impacts of the probabilistic approach, which can be used as the basis for the implementation of algorithms for automating the corresponding calculations during the design and operation of buildings and structures. The article also develops a technique for constructing finite elements, which makes it possible to consider the stress-strain state of deep-laid pile foundations for bridge supports on an elastic base with piecewise constant parameters. The developed technique based on the properties of Fourier images of finite functions, which allows calculating piles with end and surface widenings for dynamic effects.

In the article there will be a consideration of collapse process progressive simulation of a high-rise building by removing the first-floor columns. The object of the study will be a 27-storeyed high-rise building. The high-rise building structural concept will consist on a monolithic reinforced concrete frame. The mounting base structural concept has been modeled as absolutely rigid. Static and dynamic calculations have been performed in the «Ing +» software complex, while the wind load pulsating component was taking into account using the finite-element method for the spatial slab-and-rod model. The dynamic calculation analysis has shown the obtained oscillation forms corresponding to the design requirements. The stress-strain behavior has been studied for the floor slabs as reinforce constructive of a typical floor. Structural concepts for the building frame of a high-rise building have been developed to reduce the progressive collapse risk. In the physically non-linear calculations, with the removal of the first-floor corner and central columns, four options for the sandwich floor slabs reinforcing were taking into account. The rational reinforcement option has been selected, in which the building is resistant to progressive collapse. The building frame structural concept with the floor slabs heavy-duty reinforcement of the first five floors has been suggested. An outrigger floor with encircling reinforced concrete trusses along the outer contour was included to reinforce the load-carrying framework. Recommendations on the choice of rational structural concepts, reducing a high-rise building progressive collapse risk have been given.

Purpose Increasing awareness of the society and complying with design requirements of building codes for seismic safety of structures and inhabitants during severe earthquakes are the primary purpose of seismic analysis. This study aims to present the variability in seismic fragility functions for frames of different heights for the most vulnerable condition of structure using nonlinear time history analysis. Design/methodology/approach A total of 4, 8 and 20 stories reinforced concrete (RC) moment-resisting two-dimensional frames are considered for this study. Ground motions (GM) are selected as per the conditional mean spectrum and these are conditioned on a target spectral acceleration at the concern time period. RC frames are designed and detailed as per Indian standards. A concentrated plasticity approach is adopted for non-linear analytical modeling of the RC frames. Deterministic capacity limit states in terms of maximum inter-story drift ratio are considered for different damage states. Fragility functions have been derived following a lognormal distribution from incremental dynamic analysis curves. Finally, the maximum likelihood estimation of the response is obtained for fitting curves with observed fragility. Findings The fragility functions of the three structures reflect that under critical or extreme conditions of GM the taller buildings have higher fragility than the shorter buildings for each level of limit states even though both are designed to meet their code-level design forces. Research limitations/implications The study is conducted on the extreme scenario of GM conditioned on the fundamental time period of each building, whereas comparison can be developed by selecting various methodologies of GM set. The probabilistic capacity model can be developed for future studies to check the fragility variation with deterministic and probabilistic capacity. Originality/value The investigation endeavors to present a comprehensive fragility assessment framework by analytical method. The outcome will be useful in the development of a disaster management strategy for new or old buildings and the response of seismic force with a variation of the building’s height. The findings will also be useful for updating the earthquake-resistant building codes for the new building construction in a similar context.

In the design of pile foundations, stiffness of the frame is neglected and superstructure is analyzed without considering the flexibility of soil mass. This leads to the inaccurate estimation of design forces (shear force and bending moments) and settlements. ANSYS software which is based on finite element method is used to analyze the influence of sand bed relative density of (35 and 70%), and pile spacing (3D and 4D) on the behavior of building frame supported by group of piles (2×2) when it subjected to vertical loads. Differential settlement and rotation are observed in case of the pile supported building frame. In addition to the pile cap rotation, pile head deflection in the horizontal direction is observed which is due to the interaction of super structure with substructure. The bending moment is negative for the dense sand compare to lose sand because of the more restraint of the piles even at the top layers.

Structural damage inspection after an earthquake is essential for safety assessment of the affected wood-frame buildings and for making knowledgeable decision regarding their repair, renovation, or replacement. We present a polarimetric radar system for sensing the concealed wood-frames damaged by earthquakes. This system employs an antenna array consisting of four linearly polarized Vivaldi antennas recording full-polarimetric radar echoes in an ultra-wideband ranging from 1 to 20 GHz. The detailed design of the system and the signal processing algorithms for high-resolution 3D imaging are introduced. We conducted a number of surveys on damaged wooden wall specimens in laboratory. The experiment results indicate that the high-frequency radar waves can penetrate the wooden walls. Deformations of wooden structures (about 2 cm displacement) inside the wall, as well as the concealed small metal nails (about 3 mm in diameter and less than 2 cm in length) and bolts can be clearly imaged. The shape and orientation of the wooden members have shown a great sensitivity to the radar polarization. It is concluded that radar polarimetry can provide much richer information on the condition of concealed building structures than the conventional single-polarization subsurface penetrating radar.

This paper presents the experimental results of static vertical load tests on a model building frame with geotextile as plinth beam supported by pile groups embedded in cohesionless soil (sand). The experimental results have been compared with those obtained from the nonlinear FEA and conventional method of analysis. The results revealed that the conventional method of analysis gives a shear force of about 53%, bending moment at the top of the column about 17% and at the base of the column about 50–98% higher than that by the nonlinear FEA for the frame with geotextile as plinth beam.
