Living in anachronistic space: Temporalities of displacement in Moscow's Soviet-era standardised housing

In 2017, the Moscow municipality announced the demolition of several thousand remaining Soviet-era, standardised apartments (khrushchevki). Known as the Renovation, the renewal project promises to replace the khrushchevki with new residential districts. Based on fieldwork in Northern Izmailovo, a district targeted for demolition, this article analyses encroaching displacement by foregrounding the temporal experiences of affected residents. Building on literature that explores the political underpinnings of discourse and aesthetics in urban renewal projects, with particular attention to Rancière's temporal politics, the article contends that the Renovation depends on the discursive construction of its targets as spatial anachronisms. This renders the Soviet-era housing blocks, and those who live within them, vulnerable to a spectrum of modernising aestheticising interventions—from minor ornamentation to wholesale demolition. Based on ethnographic data, the article shows how the initial stages of redevelopment have altered a local network of benches. For a group of long-standing, elderly residents, these disruptions have instigated more profound reckonings with their own sense of time in/and space, leading to an understanding that they, too, are seen as anachronistic features of the city. Paying attention to urban materiality on a granular scale, particularly in standardised housing estates, reveals the multifaceted temporalities that inform residents' engagements with the spaces of their home districts. The article argues that doing so counters the exclusionary temporal logic of the discourse of anachronism by denying its ubiquity. In turn, it speaks to growing geographic interest in amplifying alternative temporalities in the face of destructive, terminal change.     

The Numerical Study of Base-Isolated Buildings Under Near-Field and Far-Field Earthquakes

The behavior of base-isolated building frame is investigated with the help of a numerical study for far-field and near-field earthquakes with directivity and fling-step effects. Both design-level and extreme-level earthquakes are considered. Selected response parameters are peak floor displacement, acceleration, base shear, and isolator displacement. Inelastic behavior of base-isolated structure during the earthquake is investigated performing nonlinear time history analysis of a ten-story building frame. This study shows that base isolation is not effective for near-field earthquakes. Even for design-level earthquake, the frame gets significantly into inelastic range for earthquakes with fling-step effect.     

Inelastic Displacement Ratios for Nonstructural Components Subjected to Floor Accelerations

This paper describes a study on the characterization of the Inelastic Displacement Ratios (IDRs) of inelastic acceleration-sensitive nonstructural components subjected to floor accelerations obtained from the linear analysis of multistory building structures under far-field ground accelerations. Several building models having different structural systems and a number of stories were considered. IDRs were obtained from the displacement response of elastic and inelastic single-degree-of-freedom systems subjected to floor accelerations. Similarities and differences between floor acceleration IDRs and ground acceleration IDRs were identified, and efforts were made to explain the differences. Finally, a predicting equation for floor acceleration IDRs is proposed and validated.     

Isotopic Composition of Lead in Copper Ores and a Copper Artefact from the La Profunda Mine (León,Spain)

This paper continues the characterization of the lead isotopic fingerprint of ancient copper mines in the north‐west of Spain. In this work, the lead isotopic compositions found in copper ores from the La Profunda mine are presented. Azurites and malachites sampled from this deposit were subjected to lead isotope analysis by multicollector ICP–MS. The results showed a clear radiogenic lead signature compatible with the presence of uranium‐rich minerals (such as zeunerite) in the same mining complex. Moreover, a rare copper artefact, found in the galleries of the mine during its modern exploitation, was also analysed and showed that local mineral was used for its manufacturing.     

Contested migration and settler politics in Cyprus

Immigration and settler literatures provide contrasting approaches to the evaluation of conflict between ‘newcomers’ and ‘indigenous’ groups. On the one hand, immigration studies emphasize that newcomers, particularly migrants, almost never fight civil wars; on the other hand, studies on settlers in contested territories expect inherently unstable relations between settlers and native populations affected by colonization projects. While each provides strong evidence to support its argument, neither literature has adequately accounted for hybrid cases where the settler and migrant categories have become almost indistinguishable. The article focuses on Cyprus as a paradigmatic such case. Specifically, it looks at populations transferred from Turkey to the northern part of the island after 1974 described either as settlers or immigrants by rival accounts in the Cypriot conflict. While colonization constitutes a violation of international conventions and a major obstacle to peace, settlers in such places as Cyprus, Tibet or Western Sahara often meet the profile of migrant populations more interested in daily survival issues than in territorial politics. In contrast to other historical or contemporary cases of settler colonialism such as Algeria (France) or West Bank and Gaza (Israel), what is particularly puzzling in Cyprus and elsewhere is the absence of mobilization and politicization among settlers despite perceived discrimination and fear of relocation following a negotiated peace agreement. Addressing this puzzle is essential to bridging the gaps between immigration and settler literatures and in mediating the tensions between conflicting claims over space, land and the political geography of peace settlements in deeply divided societies.     

Applicability of Pushover Methods to the Seismic Analyses of an RC Bridge,Experimentally Tested on Three Shake Tables

The applicability of different pushover methods was analyzed on the example of a bridge, which was experimentally tested on three shake tables at the University of Nevada, Reno. The response of the bridge was quite complex. The intensity as well as the direction of the deck torsional rotations varied significantly, depending on the seismic intensity. At the low intensities, all the employed pushover methods estimated the displacements of the deck very well. In the case of strong earthquakes, the advantages of multi-mode and adaptive methods was demonstrated.     

An Analytical Study on the Seismic Vulnerability of Masonry Buildings in India

Two analytical models for unreinforced masonry (URM) buildings are proposed with the aim to simulate their seismic response and to estimate corresponding vulnerability functions. The proposed models are implemented in SAP 2000 nonlinear software to obtain capacity curve parameters for representative Indian URM buildings, based on a field survey and statistical analysis. Vulnerability functions are estimated using the obtained capacity curves. Damage Probability Matrices (DPMs) are obtained using the approximate PGA-intensity correlation relationship as per Indian seismic building code and are compared with the commonly used intensity scales and empirical damage data observed after the 2001 Bhuj earthquake.     

Dynamic Stability and Design of C-Bent Columns

Symmetrically reinforced bridge columns with a horizontal cantilever in one direction, called C-bent columns, tend to deform predominantly in the direction of applied moment when subject to strong earthquake shaking. For this reason, the strength in the direction of applied moment is generally increased in design. This article describes the use of inelastic dynamic time history analyses with a suite of ground motion records to quantify the amount of strength increase required to minimize likely peak and permanent displacement demands. It is shown that the strength should be increased by approximately 2.3 times the applied moment in design.     

Elastic Displacement Spectrum-Based Design Approach for Buckling-Restrained Braced Frames

The design focus for a buckling-restrained braced frame (BRBF) is that the buckling-restrained braces (BRBs) dissipate most of the seismic energy while the main frame retains a degree of elastic stiffness under a major earthquake. An elastic displacement spectrum based design method is presented in this article, which can directly determine the sectional area of the BRBs. The yield displacement in the roof of the main frame is taken as the target displacement under a major earthquake. An elastic displacement design spectrum is used to solve the target period of the BRBF. To validate this method, a six-story buckling-restrained braced steel frame is designed using the proposed method, and a series of nonlinear response history analyses (RHAs) are performed to verify the design result. The example shows that the required BRB area can be simply and accurately determined by the proposed method. The error between the given target displacement and the RHA results is 4.0% and 21.3% for BRBFs designed with BRB yield strength of 235 Mpa and 100 Mpa, respectively.     

Seismic Rotational Displacements of Gravity Quay Walls Considering Excess Pore Pressure in Backfill Soils

The effect of excess pore pressure developed in backfill soil during earthquake is an important consideration in rotational displacement prediction of gravity quay walls. Based on Newmark’s sliding block concept and stress-based excess pore pressure model, a new method is proposed to predict the critical rotational acceleration and angular acceleration time histories considering the development process of excess pore pressure in earthquake events. Then, the rotational displacement of gravity quay walls is predicted according to the calculated angular acceleration time histories. By using the proposed method, the effects of various parameters involved in the calculation have been studied by carrying out a parameter study. Analysis results reveal that the influence of excess pore pressure on the rotational displacement of gravity quay walls with saturated backfill soil is significant, so, can not be ignored; and rotational displacement is sensitive to the magnitude of earthquake, horizontal and vertical seismic accelerations of ground motion, wall and soil friction angle, and soil relative density. When the rotation and sliding of wall occur simultaneously, rotation and sliding will be inhibited by each other.
