The Ultimate Bearing Capacity Of Cast Banban Corner Cracks Cracking Mechanism And Cracking Board Analysis

The cast-in-place concrete slab structure now is a widespread and adoptive structure form in industry and public building. But the 45 degrees plank cape inclined crack within the concrete building plank structure have become the widespread form that the building plank structure crack opens the exhibition now, brought the very big bane to the safety, applicability, durable of the building, becoming a little bit hot problem of the engineering quantity.This text makes use of a procedure of ANSYS to analysis the lading stress of the inclined crack of cast-in-place concrete slab first. Setting up the mold according to the actual structure, inquirying into the influence of tensile stresses in the case of the variety of the structure respectively to the plank cape, we get basic regulation of the plank cape tensile stresses. Then, according to the existing cultural heritage data, put forward formula of stress in the case of the shrink stress and temperature stress. Through combine the example of engineering , analyzing the variety of stress in the shrink stress and temperature stress and lading stress, we inquiry into the variety of next three power of different environment.This text analyzes the difference reason of the flexible theories for concrete slab of four directions fixed and procedure of ANSYS for concrete slab of the beam ~ plank structure. This text discove new path to low stresses of plank cape through reasonable arrangement of pillar.Making use of the plastic theories, analyzes the influence of limiting bearing power in the plank of 45 degrees inclined crack and got relation between the number of inclined crack and the limiting bearing power. Then making compare with solution of FEM and analyzing the process change regulation of the concrete stresses and steel bar stresses, we provide the theory physically for the engineering...
