Honestly, planning to crash is not a good way into approaching Crit racing. Can it happen? - Yes. Will it happen? - Dependz... maybe.
It certainly will if you don't have skills, and understanding of Crit Dynamics...
The frame is somewhat important, but as important are key components, Bars, stem, saddle, cranks, WHEELS.
My own experience is extensive for Crits, albeit quite some decades ago... But tactics and skills haven't changed that much. And I can remember 3 crashes, all pileups in front of me. Never trashed a frame, some light rash from 1, scratched up an RD, and twisted a front wheel after striking a guy who went down in front of me. I always preferred the inside line, which kept me out of many problems, especially those which were the result of others poor cornering.
Frame - again somewhat based on Old Skool, but things which can apply.
Somewhat shorter Front-Center, HT at 73 deg + (not below - my custom Crit had 73 3/4 deg on a 58 frame), ST of 73.5 deg, all current race frame chainstays are fine/short, as small a BB drop as possible, Mine was 66, but 68 is okay. The Shorter Front -Center meant shorter TT... which allows one to have narrow bars 38cm and a longer stem 12-13 cm. Makes for quick handling without becoming 'twitchy'.
Higher BB means less chance of catching pedal/shoe on tight corners - that doesn't mean one shouldn;t have cornering skills, but does help, sometimes.
so, 38 bars (for me, I do have broader shoulders), 13 stem and went to 12 in '85 when I became 'Vet' (Masters now...). Short nose saddle which was 'flat and had some forward/backward sitzbones support. Short nose allowed havng saddle a bit more forward that std road saddle and still be inside saddle setback regs (Spec Power saddle seems to mimic that now).
170 Cranks (as opposed to 172.5 on my road bikes), allowed me a quick spinup of rpm, and also added a bit more clearance for cornering. Many races were on old City Streets, back east, of very questionable quality. I was never a big muscle guy, sortta normal muscle type, and riding track regularly also had me comfortable sprinting at up too 140+ rpm, and apropos gearing to match.
WHeels/Tires, very important. Sturdy, but also comfortable. I haven't ridden deep dish wheels in a Crit environment; but my impression is that they could be more 'harsh' than more moderate section depth rims. Crit are extrememly tight formations, and often you will be hitting road imperfections which you can;t see, or not in time, for the first few laps... A wheel set which tracks smoother over this stuff means more predictable control. Hars hits when you're under stress from an attack can spell problems... Good, confident tires at a reasonable pressure - very important.
And the handling and racing skills...
Good luck
