Analysis of the Vertical Dynamic Response of SDCM Piles in Coastal Areas

Journal of Marine Science and Engineering
The stiffened deep cement mixing (SDCM) pile, as a new type of rigid–flexible composite pile, significantly enhances the vertical bearing capacity of traditional precast piles, thus holding broad application prospects in the substructure construction of ...

Development of a glass microbubble-based lightweight strain hardening cementitious composite (LW-SHCC): Experiment and numerical simulation

Case Studies in Construction Materials, 2023
In this study, lightweight strain hardening cementitious composites (LW-SHCC) was developed through mix proportion design and experimental tests. The modified Andreasen and Andersen (A&A) model was applied for dry materials mixture proportioning and ...

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Bending behavior test and assessment for full-scale PC box girder reinforced by prestressed CFRP plate [PDF]

, 2015
This paper focuses on behavior of full scale prestressed concrete (PC) box girder with difference degrees of damage derived from service stage. According to typical structural damage, strengthening measures are proposed, including gluing steel plate ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Comparing the rigidity of the prestressed and non-prestressed foundation [PDF]

, 2016
If compared with reinforced concrete, the prestressed concrete is able to resist higher loads before cracks develop. As cracks reduce considerably rigidity of the element, the prestressed element can be regarded as rather rigid.

Predicted vs Measured Initial Camber in Precast Prestressed Concrete Girders [PDF]

, 2017
Prestressing of concrete is the introduction of permanent internal stresses in a structure or system in order to improve its performance. Concrete is strong in compression but weak in tension.
