Based on the experiment of five full-scale small-sized fly ash hollow block walls under low-cycle reversed load, the influence of aspect ratio, common horizontal reinforcement, size of structural column section to the loading process, failure characteristics, cracking load, ultimate load, deformation, ductility, stiffness and energy dissipation of the walls was studied. Simultaneously the mechanical properties and work mechanism of the small-sized fly ash hollow block wall has been analyzed.

Microstructure And Mechanical Properties

This paper presents the results of an experimental study on the behavior of fly ash-, bottom ash-, and blended fly and bottom ash-based geopolymer concrete (GPC) cured at ambient temperature. Four bathes of GPC were manufactured to investigate the influence of the fly ash-to-bottom ash mass ratio on the microstructure, compressive strength and elastic modulus of GPC. All the results indicate that the mass ratio of fly ash-to-bottom ash significantly affects the microstructure and mechanical properties of GPCs

Laminated Bamboo Lumber

This paper presents and discusses the experimental study on the mechanical properties of LBL column both under axial and eccentric compression. The results shows that the ultimate load for the eccentric compression specimens with the eccentricity values of 30 mm and 110 mm are 95.2 kN and 31.8 kN respectively. Eccentricity is one of the main influencing factors for the ultimate bearing capacity of the LBL columns. Because of the vulnerability of the mechanical connections or natural nodes to tensile stress and secondly, laminated bamboo is vulnerable to defects that has more detrimental influence on the tensile resistance of the material. The variation in strain for the laminated bamboo lumber column sections is linear throughout the loading process, following standard normal section bending theory which is similar as that for the beam.

Shearing Strength

According to the typical loess in Shuozhou in Shanxi province, tests involved in compaction characteristics, shearing strength characteristics and disintegration are carried out by using loess and three kinds of improved loess, namely lime and fly-ash, lime and cement, cement and fly-ash. The best improved soil method is selected. The test results indicate that the compact hybrid structure is formed by fly ash and loess. The activity of fly ash is activated as a result of the lime mixing. A series of hydration reaction prompt the intensity of modified loess. And the physical and mechanical properties of improved loess are improved noticeably.

This article studies the deformability of Fang Ren Glass Cloth in strengthening autoclaved fly ash brick masonry, based on the experiment of the mechanical behavior of specimens under single-direction loading. It also analyzes grid sticking method and the effect of U、L trim strips anchoring of specimens. One polymer mortar specimen and three strengthening specimens are used in the experiment. The results illustrates that the cracking load、ultimate load and deformability of strengthened masonry are higher than the un-strengthened one. The study has also shown that anchoring is important; the effect of strengthening is remarkable when anchored well.

Shear Span

Based on the flexural-shear and press-flexural-shear test of four scale HSW model building with High Shear-Span Ratio, The seismic behavior of the slit and integral HSW are discussed, then the failure characteristics and capacity of HSW under Vertical load and seams are analyzed. The result of experimental study proves that the ductility and the property of energy dissipation of HSW are well; Vertical load could increase the capacity and deformation, decrease the energy dissipation of HSW. And the seams of wall could improve the ductility and the property of energy dissipation of HSW , lower the capacity.
