This paper summarizes an engineering experience of solving the problem of thermal cracking in mass concrete by using a large project, Zhongguancun No.1 (Beijing, China), as an example. A new method is presented for controlling temperature cracks in the mass concrete of a foundation. The method involves controlled cycles of water circulating between the surface of mass concrete foundation and th...

Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behavior has been developed to strengthen the concrete structures over the recent few years. In this paper,...

The article discusses well-known and perspective constructive technological systems for the installation of monolithic precast-monolithic floor slabs civil industrial buildings. It shows examples expediency using all kinds inserts made plastic other light materials products replacing a part heavy reinforced concrete. An original resource-saving method with simultaneous increase in degree their ...

Abstract In order to study the influence of arrangement thermal insulation floor on and mechanical properties hollow slab, ABAQUS is used establish model analysis behavior slab. By investigating distribution temperature, heat flux, damage deformation floor, mid-span deflection other characteristics section, it concluded that although transmission can be effectively obstructed by will transferre...

This paper presents an experimental investigation that focuses on the flexural behavior of innovative reinforced concrete–ultra-high performance concrete slab with expanded polystyrene lightweight core. type is proposed to serve semi-precast solution, in which bottom layer ultra-high working as a formwork during construction slab, used for reduction structure self-weight, and top normal designe...
