In this paper, construction staged-analysis is introduced to understand how the additional loads transfer to existing and added piles. Added piles are not able to take on the existing load due to mechanical problem.

This experimental study investigates the influence on the tensile behavior of strain-hardening cement composite (SHCC) with HR and SWP Shrinkage Reducing Admixture (SRA). SRA can also improve the tensile strength and multiple cracks of SHCC material used in this study.

This experimental study investigates the influence on the flexural behavior of strain-hardening cement composite (SHCC) with HR and SWP Shrinkage Reducing Admixture (SRA). SRA can also improve flexural strengths and flexural toughness.

This experimental study examines the test results on the flexural behavior of strain-hardening cement composite (SHCC) with two types of Shrinkage Reducing Admixture (SRA). An influence of SRA on the flexural behaviors of SHCC mixes was observed.

As the scale of structure becomes larger, the temperature crack of massive concrete structure is caused by the phenomenon which the mass concrete volume is restricted in the inside or outside part due to the temperature variations induced by the hydration heat of cement. So, we should prepare the method to reduce reasonably the hydration heat for the control of temperature crack. Therefore, this study presents the hydration heat analysis to verify the control effect of temperature crack when we consider to the different concrete mixtures.

To evaluate seismic performance of existing school buildings, This study performed pushover analysis using Midas/Gen Ver.795. The outcome shows that building have insufficient seismic performance and seismic reinforcement is necessary to have enough seismic performance.
