Strut-And-Tie Modeling Of Multistory, Partially-Grouted, Concrete Masonry Shear Walls With Openings, Jeffrey Ryan Buxton
Strut-And-Tie Modeling Of Multistory, Partially-Grouted, Concrete Masonry Shear Walls With Openings, Jeffrey Ryan Buxton
Theses and Dissertations
Construction practices are constantly evolving in order to adapt to physical locations and economic conditions. These adaptations may result in more cost-effective designs, but may also come at a cost of strength. In masonry shear walls, it is becoming more common to reduce the amount of grouting from every cell to only those with reinforcement, a practice known as partial-grouting. Partially-grouted masonry responds differently and in a more complex matter to lateral loads as compared to fully-grouted masonry. The response is made even more complex by wall discontinuities in the form of openings. The main objective of this study is …

Structural Lightweight Grout Mixture Design, Hannah Jean Polanco
Theses and Dissertations
This research focused on designing a grout mixture using lightweight aggregate that achieves the minimum 28-day compressive strength required for normal-weight grout, 2000 psi. This research specifically studied the effects of aggregate proportion, slump, and aggregate soaking on the compressive strength of the mixture. The variable ranges investigated were 3-4.75 parts aggregate to cement volumetrically, 8-11 in. slump, and 0 and 2 cycles of soaking. The statistical model developed to analyze the significance of variable effects included a three-way interaction between the explanatory variables. All three explanatory variables had a statistically significant effect on the grout compressive strength, but the …

Seismic Analysis Of And Provisions For Dry-Stack Concrete Masonry Wall Systems With Surface Bond In Low-Rise Buildings, Joseph G. Eixenberger
Theses and Dissertations
Masonry is one of the oldest forms of construction materials that is still in use today. However, construction practices in the modern age demand faster and more economical practices. Dry-stack masonry, or masonry that doesn't use mortar to bind the blocks together, is a unique system to make masonry more economical. Though several systems of dry-stack masonry have been suggested little to no data exists as most of these systems are patented. This research used dry-stacked normal weight concrete masonry units with an eccentrically placed reinforcement. The wall system is connected through a surface bond and lacks any geometric connection. …
