What kind of spiders are large red with black stripes?

It is also called a Black and Yellow Garden Spider, Argiope aurantia, the spider from Charlotte's Web. All Spiders have venom, but very few will bite people and even fewer are dangerous. The Garden Spider minds its own business and stays in it web. It is not aggressive. - http://www.whatsthatbug.com/2009/08/20/19208/
