Last fall, my local lumberyard began stocking EZ-Tube modular footings from EZ-Crete (e-zcrete.com). Designed to replace a conventional pier footing with a spread base, each stack of precast concrete sections is tied together with a galvanized-steel rod. I recently gave the product a try ...
Dig the hole, drop in the sections, backfill, and you’re ready to build—or, at least, that’s what the manufacturer claims. But whether you’re pouring in place or using a precast pier, there’s no getting around the fact that you’ll need to dig and backfill the footing holes....
footing. It avoids taking considerably more mainline traffic out of service (to perform the excavation to build a spread footing). It allows for faster construction as all elements are precast. It eliminates the need for constructing formwork,reinforcement steelplacement, concrete pouring, and curing...
We offer a diverse range of precast concrete solutions for building, construction, EV charging, solar, electrical, utility, telecom professionals, and homeowners.

The main objective of the transverse joint between prefabricated full-depth precast concrete deck panels is to prevent the relative vertical movement betwe... HL Stefaniuk,AA Semendary,D Svecova - 《Advances in Structural Engineering》 被引量: 0发表: 2024年 Experimental and Numerical Analysis of ...
Strut-and-tie models (STM) have been developed for original and repaired precast reinforced concrete (RC) bridge assemblies tested under quasi-static cyclic loads. The original assemblies, built using accelerated bridge construction techniques, are half-scale column-to-footing and column-to-pier cap...
concrete spalling was avoided. Mashal and Palermo (2019) tested a bridge bent with low-damage seismic designs. The top and bottom ends of the precast columns were armed with steel jackets. The contact interfaces between the columns and the footing or the cap beam were also armed with steel ...
In the other model, a built-in elastomeric pad integrated with the footing and a concrete segment constituted the plastic hinge (SBR-1). The purpose of using the pad was to minimize damage while dissipating energy through yielding of the longitudinal bars and deformation of the pad. Both ...
For precast bridge piers, the performance of pier connection determines the seismic capacity of the whole bridge. Therefore, a new connection between precast bridge column and footing using ultra-high performance concrete (UHPC) is developed in this paper. The precast column and footing are ...
