Arthritis &Rheumatology, EarlyView.Objective Systemic lupus erythematosus (SLE) shows clinical and molecular heterogeneity, and cardiovascular (CV) complications and lupus nephritis (LN) remain leading causes of morbidity and mortality. This study investigated whether omic profiling can reveal molecular endotypes linked to these outcomes.

Drift Capacity of Reinforced Concrete Walls with Lap Splices
, 2021 Twelve large-scale reinforced concrete (RC) specimens were tested at Purdue University’s Bowen Laboratory to evaluate the deformability of structural walls with longitudinal lap splices at their bases. Eight specimens were tested under four-point bending

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading
Structural Concrete, EarlyView.Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

International Journal of Concrete Structures and MaterialsThis study proposes a novel method for damage assessment in reinforced concrete beams using bonded piezoelectric transducers (PZTs). By analyzing the transmission and reception of high-frequency waves through PZT pairs attached near lap splices in ...

Splice Strengths of Noncontact Lap Splices Using Strut-and-Tie Model [PDF]
Journal of the Korea Concrete Institute, 2007 Strut-and-tie models for noncontact lap splices are presented and parameters affecting the effective lap length and the splice strength are discussed in this paper. The effective lap length along which bond stress is developed is shorter than the whole lap length.

Rotation capacity of continuous reinforced concrete slab strips revisited
Structural Concrete, EarlyView.Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Special Length Priority Optimization Model: Minimizing Wall Rebar Usage and Cutting Waste
BuildingsThe production of steel rebar is an energy-intensive process that generates CO2 emissions. In construction, waste is generated by cutting stock-length rebar to the required lengths.

The challenges of GFRP RC beam design for limit states
Structural Concrete, EarlyView.Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Comparative study of factors influencing tension lap splices in reinforced concrete beams [PDF]
, 2020 The practice of splicing reinforcing bars in reinforced concrete structures to manage insufficient bar length is a common approach, which is mainly due to transportation limitations on bar length.

International Journal of Concrete Structures and MaterialsSudden failure of reinforced concrete (RC) beams with substandard tension lap splices due to low resistance to flexure is a critical issue that needs to be addressed. Accordingly, a novel pre-stressing technique is presented in this paper, which offers a
