The inspection of on-ground circular concrete tanks by the authors has shown that the formation of horizontal cracks in tank walls is a common serviceability issue in Australia. These cracks often lead to leakage or durability-related issues that impact the service life of tanks. In this ...
Horizontal cracks, bulging, or wall leaning is sometimes due to damage during construction, a condition that's actually pretty easy to recognize. Here we will describe the types & causes of horizontal cracks in the mortar joints of a concrete block wall or foundation wall that is damaged during...
The reinforced concrete shaft of a RCW, commonly called caisson, used to be poured in-place and in sections (Spiridonoff1964). This tedious and time-consuming procedure has been replaced by using pre-fabricated rings (segments) of reinforced concrete which can be easily assembled on-site (Figs...
This paper describes a new method of analysis and design for steel frames with concrete or masonry infilling walls subjected to in-plane forces. The method... A Saneinejad,B Hobbs - 《Journal of Structural Engineering》 被引量: 439发表: 1995年 A kinematic FE limit analysis model for thick ...
Study on concrete temperature control and crack prevention of Erhe new sluice on Huai River canal diverting flood into see AbstrcatConcerning the common phenomenon that there often exist the vertical cracks in new sluice piers at early-age concrete, which are almost vertical an... Y Zhu,J Yang...
Hollow prestressed concrete girder and method for manufacturing thereof PURPOSE: A hollow prestressed concrete beam and a manufacturing method thereof are provided to effectively control tension cracks on the top of the concrete beam when compressive force is applied to the beam. CONSTITUTION: A hollow...
Ignition was initiated in the same location and the amount of air leakage area was controlled by filling cracks around the doors and windows with fiberglass insulation. Of the seven experiments, Experiment 3 had a slower growing fire and Experiment 14 had a faster growing fire. The other five ...
Based on the calculation methods for the shear capacity of horizontal seam in Chinese and Japanese codes, the bearing capacity for a total of 96 specimens with six sections, four different shear span and four axial compression ratio respectively is analyzed.. Improved design equations for calculating...
The general focus of the paper is to show a method of strengthening arch bridge that has longitudinal cracks. The process is done by new reinforced concrete spandrel walls stabilized by transverse prestressed monostrands. Specifically, the paper is aimed at the reconstruction of the brick arch ...
For such analysis, a 3-D cohesive crack interface model has been developed to represent concrete fracture in a realistic manner, and an interface material law has been proposed to simulate the dowel action of steel reinforcing bars crossing cracks and construction joints. Based on the experimental...
