Smart city programs provide a range of technologies that can be applied to solve infrastructure problems associated with ageing and increasing demands. The potential for urban improvement remains unrealized, however, due technical, financial, social constraints criticisms limit the implementation smart cities concepts management. discussion presented here provides review including sensors, crowdsourcing citizen science, actuators, data transmission, Internet Things, big analytics,...

Abstract When shear cracking occurs in existing reinforced concrete deep members, engineers are faced with the challenge of determining safety members. This paper presents a crack‐based assessment approach that utilizes Two‐Parameter Kinematic Theory (2PKT) as framework for lightly beams. The three approaches progressively increasing levels approximation (LoAs). first level (LoA I) involves using 2PKT predictive manner situations where crack shapes unknown, LoA II improves upon I by...

Seismic probabilistic risk assessment requires explicit consideration and quantification of all sources uncertainty. Although uncertainties in earthquakes basic material properties, such as nominal concrete compressive strength, strain at maximum stress, modulus elasticity concrete, have been considered some studies, parameters used to model the nonlinear behavior are often not considered. Recent recommendations design standards incorporated performance-based limit states nuclear power...

Abstract In the design and assessment of thick concrete shell structures subjected to out‐of‐plane loads, there is often a need evaluate response shear critical components or influence combined loading on response. This paper first presents results from three shear‐critical large‐scale strip experiments combinations shear, moment, axial load. The were monitored with digital image correlation equipment capture full deformation field throughout loading. then simplified three‐dimensional model...
<p> This paper presents the results of twelve reinforced concrete shell elements subjected to shear and biaxial stresses. Elements were constructed by one-third scale real NPP wall monotonically loaded until failure. The compared with predictions from Modified Compression Field Theory (MCFT). compressive strength, steel yield strength reinforcement ratio APR1400 that is current model in Korea used for reference elements. And high concrete, decreasing other ultimate load was accurately...
An assessment of a four storey prestressed reinforced concrete structure is compared to existing results for full scale shake table test.The E-Defense structure, which was tested in 2010 and subjected the Kobe earthquake record, complex with rocking shear walls one direction moment frame other.This work focusses on seismic performance wall system 1990 record at three intensity levels (25%, 50% 100%), as done purpose this study assess if, rather than using heuristic approaches or experimental...
