Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Behavior and Design of Distributed Belt Walls as Virtual Outriggers for Concrete High-Rise Buildings
A new lateral force-resisting structural system for concrete high-rise buildings, distributed belt wall system, is proposed. Unlike conventional belt structures, the belt walls infilling the space between perimeter columns are distributed separately ...

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.

ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.
