The True Scale of the World’s Tallest Buildings
Skyscrapers are mainly built to add much-needed space to cities and urban areas, so it seems amiss that our standard for ranking them is based almost exclusively on height when that doesn’t explain just how big they really are or how much space they offer. To better...
Strength and Deformation of Reinforced Concrete Squat Walls with High-Strength Materials
Author(s) Min-Yuan Cheng, Leonardus S. B. Wibowo, Marnie B. Giduquio, and Rémy D. Lequesne Abstract The behavior of reinforced concrete (RC) squat walls constructed with conventional- and high-strength materials was evaluated through tests of 10 wall specimens...
Seismic Performance of Tall Moment Frames with High- Strength Reinforcemen
Author(s) Duy V. To, Drit Sokoli, Wassim M. Ghannoum, and Jack P. Moehle Abstract Seismic performance of tall, reinforced concrete special moment resisting frames with high-strength reinforcement is investigated through laboratory tests and nonlinear dynamic...
Stochasticity on Long-Term Behavior of Steel-/Carbon Fiber-Reinforced Polymer Prestressed Girders
Author(s) Yail J. Kim and David Micnhimer Abstract This paper presents the long-term behavior of bridge girders prestressed with steel strands and carbon fiber-reinforced polymer (CFRP) tendons, based on a stochastic process called polynomial chaos expansion...
Seismic Performance and Multi-Scale Model of Damage Evolution for Reinforced Concrete Frame Structures
Author(s) Yao-Rong Dong, Zhao-Dong Xu, Ye-Shou Xu, Sarwar Waseem, and Qiang-Qiang Li Abstract In this paper, the influence of axial load on the seismic behavior of reinforced concrete frame structures is assessed, and the damage of reinforced concrete frame...
Seismically Robust Ultra-High-Performance Fiber- Reinforced Concrete Columns
Author(s) S.-H. Chao, M. Shamshiri, X. Liu, G. Palacios, A. E. Schultz, and A. Nojavan Abstract Ultra-high-performance fiber-reinforced concrete (UHP-FRC) has a high compressive strength of 22 to 30 ksi (152 to 210 MPa) and a substantial shear strength as well...
Acoustic Emission Monitoring of Prestressed Girders during Fabrication and Transport
Author(s) Dryver R. Huston, Robert L. Worley II, Mandar M. Dewoolkar, and Mauricio Pereira Abstract Prefabricated and prestressed, reinforced concrete girders used as prefabricated bridge elements and systems (PBES) are common in infrastructure projects....
Mechanism of Chloride Ion Adsorption in Cement Hydrates as per Time-Dependent Behavior
Author(s) In-Seok Yoon and Tatsuhiko Saeki Abstract The purpose of this study was to explore the mechanism of the interaction between cement hydrates and chloride ions by examining the time-dependent behavior of chloride ion adsorption. The CH and AFt phases...
Steel Corrosion in Calcium Aluminate Cement Mortar against Chloride
Author(s) Ki Yong Ann, Hee Jun Yang, Hansol Kim, Jiseok Kim, Won Jung Cho, and Ho Seop Jung Abstract Three different types of calcium aluminate cement (CAC) were investigated about their resistance to chloride-induced corrosion of steel. CAC imposed higher...
