Abstract

In this paper, in order to study the wind interference effect,with change of height of the upstream building, the numerical simulation of the downstream construction disturbance of wind pressure distribution has been done. With architecture of upstream, wind pressure coefficient values of windward and leeward faces of downstream building basically reduces,and interference effect shows shielding effect.

Abstract

In order to investigate the design method of single tapping screw connections between steel plate and non-steel plate and the applicability of calculating the shear capacity of single tapping screw connections with sheet steel under 2mm according to Chinese code Technical code for design of cold-formed thin-wall steel structures(GB50018-2002),theoretical analysis was carried out on single tapping screw connections, which were distinguished by connection forms called steel plate-steel plate connections and steel plate-non-steel plate connections. The results show that: Chinese code GB50018-2002 is suited to calculate the shear capacity of single tapping screw connections with sheet steel under 2mm and the results are safe compared with test results. The design method of single tapping screw connections between steel plate and non-steel plate is given on the basis of test results.

Abstract

In order to improve the wear resistance of Al-Si alloys, the electro deposition of Ni-Co-P/Si3N4 coating on a hypereutectic Al-Si casting alloy was studied in this paper. The thickness, hardness, surface morphology, composition, adhesive force and wear resistance of Ni-Co-P/Si3N4 coating were measured by optical microscope, micro-hardness tester, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), adhesive attraction scratcher and abrasion tester. It was shown that Si3N4 particulates were uniformly distributed in the composite coating. And the effect of process parameters, such as electric current density, temperature, PH, plating time and component of electroplating bath,were obtained. The wear resistance of the coating was improved with the increase of hardness and the content of Si3N4 in the coating. It was also improved by decreasing electric current density. The adhesion of the coating was poor for increasing the content of P and Co in the coating. At the same time, the coating was hard, friable, and easy to be broken with the decrease of temperature.
